Well, I had some more problems with my truck. I destroyed another rear end in my truck, this is the second one within 20,000 miles. There isn't any real abuse that I give it, yet it broke. The size is 10.25" and there is a small screw that holds in the pin that holds the spider gears in place. That little screw sheared and the pin slides out. The first time I ended up replacing everything but the housing. This time I belive that I caught it in time. So neadless to say this time I think I can get away with just replacing the pin and screw. That sucked last time. Thanks for letting me rant Cody
