Original Rear end type on my 70 Duster

GREAT info everyone. Many thanks:thankyou: My 70 was, as stated before: VL29G0B with the B for the mothership plant of Hamtramck MI. The engine code is E44: 318, D31: 904 trans but NO rear end code. I figured being it was a L code low trim model it might have had a smaller rear end. Not that it makes much difference at this point, I enjoy finding out my car's history. I've been able to track down the guy that drove it from Denver CO. to Delta Junction ALASKA in February of 2003 and the two other Alaska owners before me. It's all great conversation when people stop to chat.
