Dan, Only thing is that I have 6 lug front disks installed so I want to keep the rears 6 lug. Are the 4x4 s-10 6 lug? I was thinking they are 5. I would think that some of the mid 50s-70s are six lug and would have a 3.36 or 3.73 rear end that should be close to being as wide as the torque tube rear I want to replace. Now I just need to find it. Thanks again for your help.
