Bellhousing bolts...

[Lost Bushman]

Will any of the bolts from the A4LD bellhousing transfer over to the FM146? The thinner ones look like they'll work with about a half inch of thread into the block, and the fat ones won't. Can I just get a couple of grade 8's to match the thin ones or should they all be changed to something else?

Also, the donor transmission I got had no clutch in it, does anyone know the bolt size/length for the flexplate?

Thanks!
