Have you priced a housing from John's Rear Ends - John's Industries. The 9" Ford Factory. or Just Rear Ends - Just Rear End's Complete Custom Crate Rear End, Ford 8 Inch and 9 Inch Third Member, Chevy 12 Bolt, Posi, Housings, Axles, Wilwood Disk Brakes ? The guys at JRE are a father/son team, small family business and they know their stuff. Unlike sheet metal, any rust on old gears creates micro-fissures in the surface, which sets them up for failure down the road. You get what you pay for, IMO.
