F23 Bolts

Can some one tell me the count and the size of bolts used to mount the F23 to the 2.2L Ecotec. Or at least the GM part numbers.


Thanks

I think 5 if I recall (one looks like a hole but is just a pilot/bushing)........ not sure on size, why not just go to a parts store and grab some grade 8 bolts, would be cheaper.

Yeah, I wasn't going to buy them from GM, just wanted the part number to reference back to a size. Its not going to be grade 8, they are metric sized bolts, right?

Do they all thread into the bellhousing, or are some into the block?

I have grade 8 bolts... I will see if I can track down a spare for the size.

All of them are block threaded except the rear( firewall) there is one that is sometimes a pita to reach, it threads into the trans.

I will have to retract that previous statement, the bellhousings are different from what I was assuming...... the bolts/mounting points may be different as well.
