Ha, yep one of the many articles I've read here recently. So I took everything to a drive line shop close by and got to talking and trusting a guy, mainly because his hands were greasy from actually doing the work. He assured me a Spicer (solid) 5-811X is what I need so I found 2 of those and as it turns out, the 2 Hermaphrodites that wobbled are actually for GM stuff.
