I used the front mount from a 90 LeSabre and it put the engine right where it is supposed to be! (I was able to check it referencing the original torque axis mount and it is in the exact same spot in relation to the body!)
The transmission actually clears everything under the hood. i was afraid the large girth would hit the inner fender, but it clears like it was made to fit! The only thing I have to do is move the ABS brake lines closer to the fender by removing the clips that separate the lines and keep them still, and then anchor them directly to the fender using some good old steel line clamps. I also have to move the ABS unit 2 inches forward to clear the transmission fill/dipstick.
It'* a tight squeeze, no question!
The front notch
A second notch in the left rear
The steering rack hits a little rib on the back of the transmission. I will remove the rib. (no pic)
I wanted to see what is was going to do in the car... now I will remove the k-member and build three transmission mounts. The engine will sit on three Energy Suspensions urethane GM transmission mounts in custom brackets (as long as they fit...) and the stock GM front engine mount. I will consider using a single top dogbone as a torque strap IF it moves around too much, but I really don't think it will.
