Will all 67-76 Abody drivetrains swap?

I'm thinking of getting a 74 dart and swapping the drivetrain into my 68 Cuda,
but am wondering if all things are equal, v8, trans, driveshaft, rearend will swap.

the 74 has a bigblock 727 auto, and the 68 has a smallblock 727 auto. I guess the only difference would be if they didn't have the same rearends, then the driveshafts would be different lengths I guess.

My 68 has an 8 3/4, I don't know whats in the 74.

Any thoughts on this?
