I believe another SS/AA racer may have run one years ago. Jim Kinnett?

The 12 bolt is the, or one of the, most efficient rears out there. Doesn't someone make a Ford 9" center section that accepts 12 bolt gears?

DeFrank & Cohen SS/AA car ran a 12 Bolt. That was in the mid 70s.

I have seen the 9" custom carrier that runs 60 gears, both straight cut and high pinion. Its an offroader thing.

I am putting dana 70 gears in my 60 housing with a power lock, now that is heavy!
