The A833 had a small (A904 sized) tailshaft in the early A's, it will go into an A904 equipped car A or F body w/o problem, I put one behind a 383 w/NOS in
an F-M-J ex POPO cruiser, still in one piece. That was after I put it in My '69 dart w/a cammed 318,.......................
Bellhousing wise, it depends on the specific one in the car, & early models used a smaller(less desirable) dia. clutch assy., so even if it had a mounting or available
bracket to use in a later A, it wouldn't be a popular effort.
