they are special bolts originally with points on the end..
made it easy to fit the bolts with the point in the factory

8 x 1.25 x 30 for the perimeter pbolts, the point was to pierce the rubber seal. There are 22 of them by memory. There's also 6 or 8 (depending on model) M10 x 1.5 x 25-3o at the fuel tank and rear torsion/shock mount and 4 x M10 x 1.5 around 70mm long at the fwd bulkhead (also by memory)

thanks Matt. Only need the perimeter botls.

If you are going to use 'normal' bolts, it my be difficult to push them through a new rubber seal. A hot 1/4" pointed steel rod [or old Philips screw-driver] pushed through the rubber, into the nut, will help.

No rubber seal needed in a drag car greg!!! Thats just extra weight!!!

30 odd bolts aren't light, either.....that's why I welded mine.😁

hoping to get away with alot less than that!!!!

10mm long should be plenty too, depending on washer choice

didnt think of that Matt,I was going to drill the centre out 4mm aswell🤪
