when I rebuilt the rear end I counted the teeth so it is 3.31. I just drive around town and run through my private( highway 59) dragstrip at times. I installed a 351c and a manual shift C4 , so rpms wont hurt it. I just need to know if the 4.10 gears will fit in a 3.31 case and carrier. thanks for all the help.
