Does anybody know the bolts needed to install the sump guard on a Spider S3 ?

I forgot to mask the threaded holes (or to leave bolt inside) before painting and now I can't see in front if it's M8 x 1.25 or fine thread M8 x 1.0. At the cross member how it's supposed to be bolted ? Previous owner just used large metal screws thru the lips of the cross member.

It's Winter here, my running 87 is stored and I don't have access to it and my 89 parts bin looks more like a snowman than an exotic car !

Thanks,

The front sway bar mounts are 8mm x 1.25. The rear at the crossmember could be whatever you want, but generally folks use the same there.

Thank you Andrew. I understand it's supposed to be bolt and nut thru crossmember lips at the rear. I will go that route.
