Here is what I should have put in the original post, have a 63 Fury with original drivetrain, the 318 poly was bad so I'm putting in a 70 318 and using the original 727 cable shift trans, the flex plate and torque converter are the originals to the 63. The flex plate, crank, and torque converter all bolted together fine, the block to trans bolted up fine except the bolt below the aligning dowel on the drivers side. As far as the torque converter register to crank goes I don't know as it seemed to go together ok.
