s10 front clip differences

Does anyone know the differences between years? More or less I am wondering about the hub to hub width. Im looking to begin a frame and just looking through all my options. I talked to Max and he thinks an s-10 clip would work very good with my truck rather than a MII IFS. So any help is appreciated. Im just looking to see how much it will have to be extended and all, so a hub to hub number would be awesome.
