Rebuilt 10 bolt posi-traction rear axle from a restored '57 Chevy. Owner upgraded to a Ford 9-inch. New in 2013: internals, powder-coat, brake lines, etc. Does not leak a drop. Excellent condition. Factory axle stamping is either AXN, AN, or AW not 100% sure on that (hard to read the stamping). Call or text Joe @ 630-220-0992. Was going to be used on my '54 project car but no longer needed. $900 pretty firm on price. My loss is your gain! Thanks for looking!
