hey guys can you please help nothing seems to fit. Bonnet apature so small that many components can't be reached.bodybody needs lifting to miss engine parts but the sill and floor distance is already 2". can see two brackets near radiator and 2 rear near number plate.must be many more support locations in addition? Live in Northants, will travel if someone can spare an hour or so to view and discuss help please thank Keith
Hi, I am almost complete with my trial fit and brackets, I will try and get some pictures at lunchtime to show what I have done, expect others may contribute also (I had similar question on rear arch support)
This was a much bigger job than expected but like most things I probably added some complication.
I have prepared all brackets in steel, plan is to remake all the front brackets/supports in Stainless now that I am happy with position and fit, getting the angles right is a pain.
Plenty of room for the everything as can be seen from the picture. Note a bolt in each corner of the GRP. You will need 6 pieces of angle measuring 50 mm long and 50x50x3 mm. 2 will be bolted to the front tabs on the chassis and 2 will be bolted to the steel diagonal braces in front of the dash. 2 more will be bolted to the tabs on the upper seat belt tube and act as pads for a generous amount of PU adhesive. The rear is then supported by the steel frame and brace bars supplied with the kit. These need the length adjusting and bolting to the subframe bolts.
The lower edge of the body sits approximately 25 mm above the bottom edge of the chassis, you then peen the overhanging alloy floor up to the GRP and bolt along the edge underside. It looks better if the alloy sits inside the GRP.
The body just drops on, couldn't be easier. The only point to remember is that the body is positioned tight up to the back of the bulge on the dash for the speedo. If your wheels arch positions appear incorrect then the dash is not in the right place and will need spacing accordingly. Please bear in mind that MK2 MX5's have a slightly longer wheel base than MK1's and a slightly taller plenum chamber. Please also remember that whilst the engine may look tall that the bonnet is nicely curved upwards for clearance. You should have no issues if you follow the above guidance. Radiator cap is accessible, brake fluid needs a funnel to fill but level can be seen easily.
Regards access space for underbonnet the biggest issue seems to be fuse / relay boxes. Different people have different solutions, couple of options on engine side but by just extending a couple of wires you can relocate to cabin side.
