Got the posi tonight and was suprised at what I found. The Yukon and Ford Racing are the same posi. If you look on Yukons website the part number is the same as the part number on the Ford Racing posi that I just got from Summit Racing. When comparing the two units something just didnt look right....







The one on the left is the new one. Why in the hell would Quick Performance send my a posi with half of the hat machined off? From what I can tell there should be no clearence issues with the aluminum case. Even if there is I would much rather grind on the case a little then cut half the material off the side of the posi and make it weak. I thought the machine job on the posi looked like crap. I could tell that someone had put it in a lathe and turned it down. Now I can see how much they took off, and its a bunch! I am begening to wonder if the posi was flexing. Crazy.....
