    I know these are scarce so I am posting this one rather than scrapping it.

    The ugly details. Open carrier with the original 2.93 gearset. It is complete, and came out of an 80,000 mile car. It was working well, but I scored a posi so I swapped this one out. I have opened the unit, and removed the carrier a couple times for measurements and swapping shims that I needed to setup my posi. So it has the original used bearings, and the shims are not setup correctly anymore. The pinion nut has been loosened and re-snugged. There is one cover bolt snapped off so that needs to be drilled and re-tapped, as well.

    So it is currently drained and would need to be at least setup for preload and backlash before you could use it.

    Case have been cleaned up mostly with media blasting and I did keep the rubber bump stops. It has the axles (31 spline) and backing plates. I even saved the the old brake hardware, if someone wanted that including drums -(11 inch dia x 2"wide). I also have a crush collar for it, that I can include, if needed.

    Price $100 OBO with local pickup (Chapel Hill, NC). If shipping is required, let's talk about it, but that may be prohibitive.

    OK, there was no interest in this rear. So I have removed the ring and pinion and sent them to a member here that can use them. If someone needs the case, carrier, axles or backing plates, I still have them. Once the virus lockdown is eased; the whole thing will go to a metal recycler. I'll re-post when that is imminent.
