You did not have to change pinion or gears, I need to learn more about this.. and your 74 is just like my 73, I looked at your thread not long ago.. Thank you for all your help and time here !!
i had to change carrier bearings because the O/D was bigger but the pinion bearing was the same O/D and I/D but i changed it anyway because all the other bearings/races were new.
