No pics right now. The 4WD S10 and S10 Blazer are the correct width. The 2wd will be to narrow. I believe any rear up to the Colorado will work, just be sure to measure and check the gear ratio. The 3:42 seems to be the most common. The axle code is normally in the golve box. GU6=3:42, GT4=3:73 but double check the stamped code on the axle tube and rotate and count to be sure. Most salvage yards don't take returns.
The S10 brackets will have to removed and new ones made to fit the old springs. This is not a bolt in swap but it ain't rocket science either.
