74 spindles and 11.75 rotors

Wheel bearings for the F/J/M body 11.75" rotors are the same as the '73-'76 A-body stuff. In fact, the whole front spindle on the F/J/M bodies can be swapped on as well. They're slightly taller, but don't believe the hype, the change is geometry is almost negligible, and actually is more beneficial than anything.

C-body and 1/2 ton stuff is a whole different story.
