I have a 904 trans, a 340 block and my trans mount won't line up on a 71 duster the only thing different is the motor originally it was a 318 car what's going on!!
trans mount wont line up either way I try it and motor mounts are correct for the 340 and mounted correctly, ill take some photos today and post it tonight. thanks for the replys and suggestions.
Your motor mounts appear to be right. May I suggest that you loosen your trans mount to the "brace". Then jack your tranny up against floor boards. Then you should have plenty of play for the brace to line up with the four holes.
exact thing happened to me yesterday when i put the 727 in my dart, i had the trans cross member on backwards, there is a kind of rolled lip and it faces to the rear of the car
