I have a 1971 Chevy 3/4 ton 2wd pick up with a rear end that is of an unknown make to me. The rear end is getting a little long in the tooth and will require some major repairs or replacement soon. I've looked for some kind of identifier (i.e. stamped numbers etc.) on the axle tube but couldn't find any. The axle tube is about 35% larger in diameter than Dana rear ends. Unlike Dana rear ends that have a removeable inspection plate only on the back side of the pumpkin, my mysterious rear end has a removeable inspection plate on both the back side and the front side. Has anyone had any experience with this type of axle? If so, what make is it and are replacement parts hard to find?
