Just drug this out of a barn in Indiana this afternoon. The "C" has been peened over, guessing at the factory. This axle has never had the numbers area cleaned off till I bought it. Will get a better pic of Cast Date tomorrow. Looks like F119 (June 11th)?
Do the guts match the code? What are the dates of the ring and pinion?
Sorry, no guts. Just a housing, backing plates and cover. There were 3 more 1st gen 12 bolt housings in the back of the barn, 1 NOS! a fiberglass 69 front "doghouse" out back and several sets of BB heads and headers of unknown engine type inside. It was dark and cob webs everywhere. I came out with the housing , set of 026 square port heads and a pair of 69 Camaro buckets and of course, my rust free trunk lid. Next stop yielded a Victor 2-R tunnel ram, 2 660 holleys a 4346 holley, a oval port strip dominator and a bunch of other stuff...I'm broke! A lot of fun treasure hunting though.
