SOLD This rear came in my 67 project car. I did not see a stamp on housing for actual gear ratio but counting driveshaft turns with both wheels off the ground it appears to be a 256 posi. It has the 72 style cover with the crease and bolt in axles. I can get pictures if there is any interest. $200.00 takes it must pick up in central NJ Thanks. PS, never drove the car so actual condition is unknown, as is, has axles and backing plates, no drums or brake hardware.
