Need help with a differential
Changing the differential fluid on my 2012 Chevy express 3500LT (L96 motor, 6l90e transmission)
Need to know what size ring gear they came with so I can order the correct differential cover gasket. Its a 14 bolt cover, differential RPO code is GU6.

With the Gasser it should be a 10.5".The 11.5 was used with the diesel. There should be a drain plug on the bottom of the housing so if your just changing the oil in the rear diff you don't have to remove the cover. RPO GU6 is a 3.42 gear ratio. Hope this helps.
