Halibrand 201 race car rear end

I believe this rear end to be brand spank'n new. I see no indication of it ever being run. 31 spline spool. Big Ford ends. Will make 57" wide rear end. You furnish " Cut to fit axles " Magnesium but the cover is an aluminum N O S Culver City, painted. $5,000.00. $500.00 discount if picked up here.
