Factory BBP on 7.25 axle

According to the info I have, the LBP 73+ 7.25 rears are 1.8" shorter flange to flange than the 72 back rears. Might make a difference if you are already tight on real estate under your car for tires.....

The 73+ 7.25 rear flange to flange is listed at 51.4"
72 back is listed at 53.2"

Interesting though, they list all 8.75 a-body rears and 73+ 8.25 and 7.25 at 53.2"
