Mr Szabo... I thought I left the bolts for the rear c/w on there??? Hmmm... Well, I believe they're M10x1.25mm but I am not entirely certain. They might be M12's at the same thread pitch. Anybody know for sure?

Hey brian, no biggie. they were there, but the HKS(?) flywheel is too thick. the flywheel is 11mm and the cw is 11mm. the bolts are 17mm long, and we decided to replace them with longer ones.. better safe than sorry

not your fault or anything negative.

 

10 x 1.25 just checked one.

And if you cant find them locally, ARP has a flywheel bolt kit for the Toyota 4A engine that uses the same thread and pitch. They are a bit to long for my fidanza aluminum flywheel.



Summit carries the kit:
