Well, I guess that's what I'm trying to find out. I can do the majority of the work myself and I also have access to a really good welder. I know the best way to go is with a pre-assembled custom aftermarket, but this is what I have to work with right now. I can probably get this thing narrowed if I need to without too much of a problem. So, I guess what I was really trying to ask was has anyone else used a truck 12-bolt in their cars and is it basically the same internally (axles,bearings,etc.) as the car version. I do appreciate your opinions, but like I said before, I have this rear in my possesion, and really wanted to try to use it if I can. Thanks for your input
