I'm with Yardape on this one. Besides, 9" housings are cheap to buy & they are easy to swap out. Pull the 3rd member & axles out of the housing & put them in a new one and be done with it. Shouldn't take more than an afternoon to swap out. You only have to disconnect the brakes, driveshaft & springs and that thing will come right out. It isn't like the front end. Once it is out, you should be able to transfer everything over in a minimal amount of time unless you swap your brakes with it.
