Just picked mine up, trying to put it on the stand but can't find the right bolts. Didn't buy mine with a trans.

What's the thread/pitch on the bellhousing bolts? I'm assuming it's metric, tried a 3/8-16 from an SBC and that wasn't happy after about 3 threads. Didn't want to push it.

EDIT: Looks like they're an M10x1.5, I used 70mm long bolts on my engine stand
