Are you sure it's not 1352- All t-5 's start with that number. I don't find anything for 120. Try to shift to 5th gear. Way over to the right & up. That's a good way to tell. If it's a 4 speed it wouldn't be worth installing with a 3.73 rear end.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
