1974 Duster wheels & tire size

No not all cars after 1972 came with disc brakes and large bolt pattern. My 1975 had drum brakes all around and 4" bolt pattern from the factory. I have since converted it to large bolt pattern and 4 wheel disc brakes. If you ordered power brakes or just got manual disc on the hi-po cars you got large bolt pattern.

What rear end came in the sbp cars after 1972? I was under the impression that all of the 8-1/4" rears and the 7-1/4" rears made after 1972 were all LBP. That is very interesting to hear. I will need to keep that in mind in the future.
