Our son was taking his truck to the shop this morning to have a rear pinion seal looked at. Well he did not make it, big mess inside. long story short looking for a rear 10 bolt 1997 GMC 1500 4x4 not sure of gear ratio it is the stock axle. any one have one? Jim Just found out that it is a 3:42 ratio the tag inside the glove box says
GU6 which apparently is a 3:42 ratio.
