This is the bracket for your Ford D70 & D70U, it actually fits! I developed these after the success of our 14 Bolt brackets and seeing what was available on the market and the problems associated with the others. The D70 was used by all of the Big 3 automakers at one time or another and they all had different uses and designs specifically for them. These are for a Ford D70 or D70U only! These are for SRW axles, DRW axles have a different offset. Both the Dodge and GM have different flanges and tube diameters. We have actually identified 4 different flanges in use and 3 tube diameters. How can 1 size fit all? So Please, don't buy the 1 size fits all available out there, you may get lucky and have it work but the odds are against you.....These also use the '75 Chevy 3/4 Ton Front Rotors and Calipers and those really cost peanuts but the rotor will need the throat opened by ~3/16".
These are not for Dual Rear Wheels, they are made for people running that axle with single rear wheels.
