.....after work today and fabbed up the reinforcement plates I need to securely mount the trans crossmember to the frame.
The lower plate that supports the ends of the crossmember is made of 3/16" steel plate, the upper plate that will sit on top of the frame rail is .140" thick.
I decided to use three 5/16-18 flat socket head screws for a neater appearance so you won't see any fasteners from the side of the car. The two 1/4" fasteners holding the plate are temporary, I'll use some 1/4-28 hex bolts.
I was able to scrounge all the materials I needed from my stash, it's good thing I never throw anything away (although my wife would most certainly disagree with that).
Another little job out of the way.
As a side note, I found out that changing out the centerlink and such for parts from a different brand GM A-body won't make any difference. I'll dimple the oil pan a little and live with the reduced turning radius, it's good thing I'm removing the B-body spindles as they just compound this issue.
