I don't think there was ever a 2-speed rear-end offered in a ¾-ton. | | | | | Joined: Feb 2007 Posts: 513 Shop Shark | | Shop Shark Joined: Feb 2007 Posts: 513 | oh well this is what he told me. but i can't believe everything my cousin says anyway

He may not know what is what if this truck doesn't drive yet,
