The holes for the bellhousing bolts in the back of the block are a 12mm fine thread. I believe they are 1.25 pitch. It is not a common thread pitch for large bolts, so you may have to do a little searching to get what you need.

Anyone know the length of these bolts? I need to pickup some other metric bolts today, so I might as well get these also...

Thanks!!! Just what I needed!!

Do these need to be Grade 8?

PERFECT! Thanks for that info.

Just an FYI, the length of these bolts was in response to a post about how long they needed to be to put a motor on an engine stand.

They are probably not the correct length to couple the motor to the tranny.

I had gotten longer bolts than that or my engine stand (I think they were 100mm or so)

anyone have these laying around so they can measure them?
