I know that the B body tip is shorter than the A body (at least mid 70's Abody) . . . the tab on the top for the hanger is the same, just would need to move the hanger to correct spot for the B body tip. Also, think the B body tip is different outlet shape (oval versus square for A body) . . . I am sure that if you get the B body tips and mock them up on your car, you can figure it all out . . .
