Where the previous owner had welded the roll cage mounts and seat mounts, the welding was terrible, bad enough I was able to pull one seat rail out by
hand!
Decided it was best to cut out the bad welds and reweld good metal in.
Went from this

via these. Not smooth finish but solid and will be carpeted.

Think about it, think about it again and then do it.

Is there any reason why you can't just shorten the propshaft and powerplant frame instead of extending the body?

Mmmm, some food for thought here.

There are 2 estate minis using MX5s that I know of. The one not pictured didnt cut the mx5 sills off so had to have wider body and it looks poo. Think
he did it that way to avoid the iva.
The one above looks good though with the exception of the arches.
I dont know of a hatchback mind.. so hopefully mine will be the first.
Wheel base is something like 20cm different and most of that can be lost in the bodywork. Although there will be a slight extension front and rear but
nothing extreme.
Im not shortening the wheelbase for 1 reason only; Why mess with a well regarded handling/drivers car? Having said that I am going to remake the rear
wishbones so the wheelbase will be approx 1-1.5" shorter.
It is an '89 but I will be mark oneing it. Rear lights, exterior door hinges etc.
I will asking plenty of questions over the next year or 2.

Started on the front suspension mounts.
This is the section I saved from the MX5.
 
Description
Simple removable jig fitted before cutting up old unit. This is to ensure angles/height etc are correct.
 
Description
Cut it up to keep the fixing bolts and shocker turret.
 
Description
Bolts welded in
 
Description
Of course there will be more triangulation but will have to wait until the roll cage is in. At least now it gives me a reference point to start at
the back.

I overlapped the edge of the MX5 floor and the mini inner sill.
I did this so I can then butt weld another piece in underneath and get a descent amount of heat into the weld. The holes are the to plug weld the said
piece in once I get round to it.
I have also migrated the original seat floor mounts in to the inner sills too.

A little bit more progress. Iv been unwell and with the weather being so cold Iv not done as much as Iv wanted.
This is the almost complete subframe/shock mounts. Still a bit more triangulation to go in but cant do that until roll cage is in. Also, the strut
brace will also be triangulated and bolted to the bulk head.
 
Description
FAO Prawnabie: I took your suggestion onboard and proceeded to shorten the wheel base by 100mm. Fingers crossed this doesnt have a negative effect on
handling.
As you can see in the picture, the subframe has a step in it which made things more difficult.
 
Description
So I made some brackets.
 
Description
Copying the standard fixings (rear subframe is held on by 3 bolts/nuts each side (but Iv only worked on the 2 towards the front as the rear bolt will
incorporate the roll cage).
The 2 outer most fixings - 1 bolt, 1 captive nut are spaced identically to the standard set up and identical side to side as I tack welded them
together before drilling the holes. The middle hole is for the standard front most captive blot to sit in. This ensured the subframe is exactly 100mm
further forwards on both sides.
 
Description
The hole that the standard bolt fitted in for alignment was them trimmed don and plug welded into the new bracket.

Bit more progress since shortening the wheelbase..
Completed the remaining chassis - subframe mountings so its back to factory.
Then remade the shocker mounts and gave it a coat of etch primer. It appears absolutely solid but will get further strength once roll cage is in.

Rolled it outside today to sweep garage floor.
 
Description
Yes, the wheel/arch/ride height looks awful but this is with no glass, interior, electrics, doors + some (well lots) metal work to complete. Once its
on adjustable coilovers and smaller wheels Im praying it will look right.

You can just see the black pen line, a flat sheet will go in here in the near future which wheel seal the entire floor.

13" it'll be going on. Which happens to be the smallest you can go on an MX5
