Okay, now that the Photo-Bucket pics are here, I can see what you have...

Front pax-side mount is here.

This is a stock 2.8/3.1 MPFI mount...

So you have an old 3.1 MPFI block then? The 3400s (and 'M' code and 'J' code 3100s too) were lacking the mount bosses to bolt this style mount to the block. Unless there is some hidden adapter behind it that I can't see, this is a positive identifier for your engine as an MPFI block. I thought yours was newer... So it has a 3400 top-end bolted to a 3.1? Funny, that is the direct opposite of what my '90 'Retta has -a 3400 block with a Turbo 3.1 MPFI top-end! :D I love GM's swap-ability!

Silly photobucket.

Chris88CL built the motor YEARS ago so my knowledge of it is limited.

So I have those 2 mounts, plus the one that attaches to the top of the Tranny, just need the 5 spd bracket instead of the auto bracket? and i need to modify the dog bone?

Hmm. Internal slave was mounted differently in Berettas from the factory. Does it have the two mounting bosses at the top of the bell housing that are needed for the old style mounts?

Ok, it does. That trans has provisions for 92+ mounts and the 91-older.
