727 trans mount in an early A ???

Once I have the 67up crossmember, I'll post side by side comparisson pics. Basically, the 65 crossmember does not hang as low, which would give the larger 727 more room. It was when I noticed my 65 crossmember is flanged front and rear versus rolled front/flange rear of the 67up that I looked at the bolt locations to the unibody.

What is actually hitting??? Is the tailshaft housing hitting on the bump stop? Or is the trans hitting somewhere else. If it's only hitting on the bump stop, try unbolting it to see if it fits. I realize all of these cars are slightly different due to factory tolerances, but that's an odd place to be interfering with. Is the engine in the stock location???

Will a 67+ crossmember work in an early A? At the very least, you'll either have to slice up the 67+ crossmember, or notch the torsion bar crossmember as pishta pointed out.
