Has anybody heard of a 6 lug 14 bolt rear-end? I just found one on the back of a friends work truck. I think its an 89 2500 2wd. I thought that there were only 8 lug 14's. Anybody know if this is full or semi floating? Or do I need more info. I want to know cause the motor just blew up and he's gonna take it to the junkyard soon.
