Phoned Westfield and sent them through a picture of the 2 identical brackets. They agreed to send me the correct part though.
I also discussed several items that I thought would be in the kit but were apparently missing:
Air box to Plenum chamber connector - the manual is a bit vague about this. It describes re-using some of the existing pipe work but most builders seem to use a piece of convoluted piping (closest I can say is like the stuff you get on a tumble drier extractor pipe). Westfield said they do not supply a part for this.
Electrical connectors - I was expecting some connectors for the lights but there were none and Westfield do not supply them.
Steering Column fixing - I was expecting a U bolt for fixing the lower end of the MX-5 steering column. Westfield send me through 2 sizes (with the missing air box bracket). I'm now unsure if the part is normally included but was missing or they were being generous!

A quick drive down the M6 and M5 and we were savouring the delights of a full breakfast in the Beefeater next to the Westfield factory.
There were a few items out of stock (exhaust connector, windscreen mountings and dashboard) so they are going to send those along in a couple of weeks. Everything else went easily in the back of the Audi estate.
I had a full list of questions to ask the guys at Westfield. The 1st of which was about the front mounting for the steering column. After looking at a chassis in the factory, we established the mounting had been welded onto the wrong part of the chassis. For the MX-5 SDV the mounting is farther back than on the standard SE chassis. The top mountings was correct (2 tabs rather than the single bracket). While we was there they fabricated a bracket which could be bolted onto the correct chassis member.
While I was there I looked at a LHD black MX-5 model they had in. I found out later that it was Gunther's (see the "Gust (Belgium)" link). It was in for a check over before going for its SVA. It was the 1st time I had seen an MX-5 based Westfield in the flesh. It's a shame it was LHD as I would have liked to see the routing of things like the steering column and brake line to the rear. Even so, we put it on the ramp so I could have a look at the diff/rear suspension and under the bonnet to see where some of the electrical items had been mounted and the routing of the air flow.

I had confirmed with Westfield that all the parts in the completion kit would fit into a large estate car which means no need to hire a van.

I didn't order anything unusual:
Trim - black
Seats - standard vinyl sports seats (black)
Seat belts - 4 point harness (black)

The first job was to remove the powder coating from inside the mountings. I looked to see if I could find a wire brush attachment or flap wheel for the electric drill but none were small enough to fit. In the end I got a bolt, removed the head and cut a slot down the shaft. I threaded some emery paper through the slot and wrapped around some foam to form a tube that was slightly larger than the mounting diameter. By squashing the foam I was able to push into the holes and attach to the electric drill.
The centre tube of the bushes is slightly longer than the outer tube. So, to push through you need something that goes around the centre tube to push the outer tube not the inner. I formed a couple of plates out of scrap metal. In effect they acted like large washers.
Now I was finally ready to fit the bushes. The vice I had wasn't really up to the job. As I tightened up the vice, the jaws were slightly at an angle so the bushes didn't press in straight.
Instead I used a long bolt through the centre with washers at each end.
By tightening up the nut on the bolt it slowly/smoothly pressed the bush into place.

I realised that how I was using/fitting the brake clips was wrong!
The clips I'd got looked like this:
They fitted okay into the 1/4" holes but weren’t very firm, held the brake pipes a long way away from the chassis and I broke several of them whilst trying to push the brake pipes onto the clip. Here is how the front pipes looked fitted (originally):
After searching for brake clips on the internet, I found a picture of some similar ones but as 2 parts! I realised that they were meant to be snapped apart and the upper part with the clip slotted into the lower part. It all made sense. The pipes only needed a bit of minor adjustments to the bends to fit closer.
The only shame was that I'd routed the rear pipes along the inside of the chassis which was no longer necessary. Having already bend the pipes and drilled the holes for the clips I decided not to change to run along the top of the chassis member.

I found a problem when coming to fit the 2 rear brake pipes. The brake clips I have seem to hold the pipes quite a long way away from the frame of the chassis. This means that if the pipes ran along the top of the chassis member, they would interfere with the fitting of the suspension arms. I decided to run them along the inside of the chassis member as from all the build pictures I have seen there is nothing in the inside that they would foul. This meant they had a couple of extra bends in them but nothing too intricate.

I initially started to remove using a hacksaw. After a coupe of cuts which removed the main part of the bracket, I decided removing using a hacksaw was going to be hard work. Part of the problem was it was very awkward to fix in a position I could cut. I borrowed an angle grinder and removed with a lot less effort.
I finished it off with a file to get a nice smooth finish.

I've finished the panel fitting for now as panels on the top of the tunnel are fitted later.
Doing all the riveting by hand without a pneumatic riveter wasn't too bad. Having said that I only did a couple of panels at a time and had some friends help for the larger panels. If you were intending doing the whole lot over a weekend say, I'd definitely recommend hiring a pneumatic riveter unless you want very sore hands!

The connection to the primary port on the master cylinder is really tight. It has to have a bent very tight to clear the clutch:
and from below:
Here is a picture of the front t-piece from underneath (it was taken after I had lifted the chassis onto its side). It shows the location of the t-piece underneath the chassis strut and how the 2 lines going to the front brakes fit a lot easier if they run along the underneath rather than the inside of the chassis:
Here is one of the pipes going from the front t-piece to the connector with the flexible lines:

I tried forming the shape on a couple of scrap pieces before attempting on the real thing. One thing that caught me was the fitting on the end that attached to the master cylinder was longer than on my test piece. It meant the bend had to be a bit tighter.
As the lines are very rigid, it was quite difficult to fit in place with the master cylinder and the T-piece in place. I found it easier to detach the T-piece from the chassis, fix the brake line to the T-piece and master cylinder, then re-attach the T-piece to the chassis.

My assumption was that the ones top right were for the handbrake. After a few posts on the forum, I have now found out they are for the bottom of the rear shocks. In fact the spacers for the handbrake are not in the starter kit. Luckily I had not tightened them so they are not damaged (someone else did the same thing and they crush when torqued up - glad to know I'm not the only one to get this wrong!).
Joe Mac (link on right) sent me the attached which shows all the spacers and what they are for:
1 : spacer for the diff
2 : headlights spacers (to put horizontaly on the bracket between the headlight and the bracket (to raise the light at the correct height)
3 : spacer to put in the diff cups (left and right)
4 : spacer for the light bracket and the rear upper wishbone mounting
5 : spacer for the handbrake (but they will be a little to long)
6 : unknow screw (today, it's still in a plastic bag !)
7 : spacer for the bottom of the shock absorber (to fit a metric bolt)
It seems I will have to wait till I get the completion kit before fitting the handbrake.

The 2 plates the pedal fixes between had been welded a bit too close together. The result was the pedal wouldn't fit between. This was solved by using 2 bolts in the hole above. By screwing them together I was able to slightly prise the plates apart, just enough to get the pedal in place:
The double thread ended bolt that holds it in place has to be passed through the brake pedal mounting. The alignment was slightly out so it had to be "screwed" through the holes using mole grips. This would all have been very tricky with the panels riveted in place.
The other 2 pedals went in without any issues:
I didn't connect the clutch master cylinder to the pedal as it will need to be replcaed to fit one of the brake pipes later:

Riveted the following panels:
- tunnel RH tunnel side
- GRP diff cover bracket
- LH front inner tunnel footwell
- RH front inner tunnel footwell
- RH (driver) front bulkhead

The manual says this about the handbrake: "Before fitting the handbrake lever it is necessary to drill clearance holes in the tunnel side panels for the two front fixings. To locate these, position a centre punch through the pre-drilled mounting holes inside the tunnel and whilst holding square tap the end. This will leave a witness mark on the outside at the point where the clearance hole must be drilled."
This all seemed quite tricky so I decided drill the clearance hole after the LH tunnel side was attached but before the RH side was fitted. The interesting part was when I came to look there weren't any pre-drilled holes in the chassis at all:
My next challenge was to find the spacers that held the front. The manual says they are 22mm. All I could find were 32mm ones below, although they fitted perfectly with the back attached to the RH side of the bracket:
I found a couple of pieces of wood to hold it in place while I drilled the holes:
and here is it fitted (with temporary bolts/nuts):
- LH and RH front inner tunnel footwell panels
- RH (driver) front bulkhead panel
- LH exterior panel
- top scuttle panel
Did the trimming of the RH tunnel side panel. I was concerned about how neat it would be after the trimming but I found that with a fine blade on the jigsaw I got a very clean cut:
this was so the panel didn't protrude below the chassis:
Trimmed the rear panel:
and some of the smaller front panels need adjustment as well:

Below is Martin demonstrating how much force is needed to pull the rivet:
and here is the finished panel:
Also drilled and riveted the passenger bulkhead:

Working out where to drill the holes in the fibreglass was very tricky. Unlike the aluminium panels, the fibreglass ones do not have pre-drilled holes. The ones along the centre tunnel were obvious. The ones diagonally across the back panel were not. To make like more complicated there is a pre-scored line in the fibreglass which you would think was the drilling line - it isn't! Luckily I had taken a picture of a finished one in the Westfield factory when I was there and realised not to follow the line. After some careful measuring I got the holes in the right place.
Here is the picture I took at the Westfield factory (it shows the variance between the line and the holes very clearly):
and here is mine:
As with the LH panel I found I had to have the panel as forward as it could go. Even so, the holes in the chassis upright at the front were right at the edge. The holes for the seat mounting needed to be elongated:
needed to trim around one of the floor chassis struts
The panel protruded below the chassis. Although not critical I trimmed back so it was flush:
