I left the stock 2wd rear end in mine, and tubbed the bed about 4" on each side to clear Iroc wheels. They sit inside the fenders enough that I want to do something about it, likely the 4wd rear end swap at some point. But at least this way I can take my time and pretty much do what I please and know I'm not going to have wheel clearance issues. I actually think it looks kind of cool in the end, I used sections of the original S10 bed sheel wells for my tubs and I like the look of it.
