What size bolts do I need? Can't figure out where I put my bolts that hold the tranny bellhousing to the block.. what size do I need?

3/8-16, whatever lengths are appropriate for your bellhousing and provide at least 3/4" penetration into the block.

I think it was 1.5" long for me.
Grade 8 for sure, and washers.

Thanks guys!

don't forget the locktite....it may save your flexplate someday...
