This is the Dana 60 under my dad's truck

Some early C10s with 396 and four speeds were equipped with the Dana 60 semi-floating axle. It has also been seen as a fleet option but it was not an RPO. There wasn't a "Max Traction package" just the locking differential option G87, sales name was "Maximum Tracttion", on trucks with the Dana 60 axle.
