Juan-
Well I did some digging and surfing on the E-net and cannot seem to even come up with a lead for ya. I never really paid attention to the availibility of the 6.75 rear axle's parts. Looks as if you'll have to keep and eye on E-bay, maybe find old overstock (NOS) parts at ford dealership, get a used, or swap out that wimpy 6.75 for a more common and easy to deal with 8" rear. I know I've crossed over and tossed my fair share of these axle assemblies without even a thought of keeping one, or parts from one. Good luck locating a Ring a Pinion. If I do cross over some info I'll be sure to pass it on.
