Does not always play well with others
Nope.Nor was my brothers '90 C 2500 8600 GVW or his '98 K2500 8600 GVW they came with 9.5 differentials. I saw hundreds of trucks come through the Dealership optioned this way. G vans came through the same way. The 6.2 diesel came with both differentials depending on options ordered.So your 88 K3500 was not a dually?
