parts interchangeability ??

Because I have no clue...
Are the early 60s As similar to the mid 60s early As? In terms of a V8 swap to a push button chassis would a '65 2-cable trans work? Would the '65 V8 exhaust manifolds work? Oil pans the same? They need the centerlink and V8 gas pedal? Do the '64/'65 engine mounts work?
