The 1970 BBB 390/Auto Javelin SST that I sold a few years ago was ordered with open dif because the original owner was a salesman and was using the car to commute long distances on the freway. This much I do know.

My 65 American never came with the posi 20 but it has it now, verse visa may apply for the Jav....Russ __________________________________ Do you Yahoo!?
