Hmm, I didn't know that the 7.5" axles work in the 8.8" rear. Are they just as strong?
ya learn something everyday
oh by the way, if you have a little more cash, then why not step up to some Moser axles for peace of mind?
Im sure you can get the 8.8" rear with a 31 spline carrier for about the same price from ford, thats what comes in the F150s isnt it?
