I have an axle housing from a 4th Gen F-body, stock 10 bolt. It's got a pinion gear in it and some axle bearings, and a speed sensor with some of the plastic broken, but that's it. No axles, no diff, no rear cover, just a bare housing.
I live in the Lancaster PA area. You can pick it up or we can arrange a meet-in-the-middle pickup. Make me any offer.
