NO! I do not need a proctologist! In my earlier message I was trying to change my rear Ford 9" diff. to a GM 4 3/4 bolt pattern for the sake of using an awesome set of wheels I found (off an S10). Consensus was to have the Ford diff. bolt pattern redrilled to the 4 3/4. In checking around, it appears that actually switching rear diffs. might be easier and cheaper. Here in Seattle area it was hard to find anyone to help and then it was expensive. So...

-can anyone recommend a GM vehicle that might have a diff. with the 4 3/4 pattern and would be the approx. correct width (sim. to the Ford 9")?
