Yep i tried putting a 9 inch pumpkin in the 9 3/8 inch housing, granted it will fit but i had to drill the bolt up holes in the pumpkin out a little for the 9 3/8s housing blots to line up with the 9 inch pumpkin. But that kind of defeated my origional porpose of keeping the limited slip 9 3/8s carrier. I also wanted to keep the 9 3/8s carrier because i figure its even a little stronger than the 9 inch. Still don't know what to do but thanks for the help!!!
