hey guys, can one of you take a look at your codes in your glove box and tell me what rpo code is for the Heavy Duty half ton 6-lug, 14-bolt 9.5" rearend with disc brakes?
These came in the some of the 05+ Vortec max, SS, and some of the trucks.
Any gear ratio is good, but it's probably going to be 3.73 or 4.10.
I need one.
thanks,
allen
