Ford 8.8 Swap
well said, 70440....
but there are snobs in every hobby, particularly cars
5.7 hemi, get your story straight before you open your mouth. Look it up, confer with E-berg, whatever it takes, the 8.75 NEVER came with discs. The rear disc Imperial you are thinking of had an 8.25.
it's even mentioned in the disc-o-tech article by E-berg.
the nature of the adjustable end-play axle bearings of an 8.75 wount allow discs to be used.....unless you adapt to the green bearings, but then you give up bearing strength/axle load
