A-body transmission conversion

Contemplating a swap to standard transmission. 1967 Barracuda, 318, 904, 7.25" rear.
I have already acquired a Ford 9" rear (drum to drum and spring perches width correct.)
I would like to upgrade to standard transmission but do not know the best way to go about it. I know I would have to change the K member, console, driveshaft, pedal assembly, etc.
Being mopar, it started to add up quickly without any real confirmation if all parts from different suppliers would work together or am I getting into a "searching for rare and un-obtainable parts list.)
(An A833 4spd would be nice, but thinking it would be smarter to go with a T5 or Tremec)

Originality is already out the window on this car and I am just looking for input by anyone who has done the conversion.

Links would be appreciated.
