i need some help identifying what year and what make automobile this 10 bolt posi rear end is out of. it has 2:41 ratio, coil springs, disc brakes, factory sway bar on the lower arms and has 5 on 5 bolt pattern. the numbers stamped on the axle tube are WN P 026 N and just below that is stamped BO63. also, from inside of backing plate to inside of backing plate measures 56". thanks for your help. also, thanks for allowing me to post on this site. sandblaster

 

WAG i'd say an impala, 5x5 is too big for a f body and disk sort of rules out trucks.
