Jerry, that info is mostly correct.

Wade, I think you would be pushing the limits of the bearing surface on the longer axles and the shorter housing.



The 79-98 axle housings are the same width.

86-93 Mustang 8.8" - 29.188" axle length

94-98 the axles were .75" longer to account for the disc brakes but used the same housing.

94-98 Mustang 8.8" - 29.969" axle length

99-04 housings are are .75" wider on each side and the axles again were lengthened another .75".

99-04 Mustang 8.8" - 30.688" axle length

The actually track width in the 99-04 rear axle assembly is 1.5" on each side giving you approximately 3" increase over 79-93 assemblies.

I believe, even today, the V6 models use a 7.5" housing and the V8 models all use the 8.8".

Please correct me if I am wrong. I may be a hair off on the dimensions.
