I swapped the 273 and 904 trans in my '65 Coronet to a 496 stroker big block and a 1965 727 trans. All bolt in other than the driveshaft. The '65 904 is a ball and trunion and the '65 727 is a slip joint. The shift and park cables are the same regardless of engine trans combination.
I took the 273 and 904 and put them in a '65 Dart which originally had a slant six. Shift and park cables were exactly the same there too. The "B" body trans was a bit long, but, a shortened ball and trunnion shaft cured that.
You may be able to use a '62-'64 727 (ball and trunnion), but you will need a '65 valve body.
