8 3/4 rear end

I have an 742 8 3/4 rear end. It is a 3.23 posi unit. The backing plates and lugs are in need of replacement and there are no brakes, but the axles seem fine. I'm not too sure what it came out of, but the leaf spring bolt holes are 44" apart and the backing plates are 51.25 inches apart (Measurements are close, but may be off slightly. I will be at the mopar nats and could bring it there. I am located just outside of Huntington, WV. Will consider trades for mopar parts, or guns.
