I have a 1981 F-body one the thick one 1.25 inches for $75 I have one on both my wagons and its just as good as the Hotchkis one I have on my sedan. I just put a coat of Zero rust on it this weekend looks great just meet me somewhere and pick it up.
I live in Fenton area, my wagon is up on my two post lift in my garage come take a look at it and how it fits. I have a 373 posi wagon rear end for sale, but its at my father inlaws house. It comes complete drum to drum and 373 gears and correct Abs senors. installed. I was told it had a Eaton Posi. I going to asking $350 for the rear end.
