I am in the middle of an S-10 frame swap on a 50' 3100 for a friend. The further I get into this project the more I wish he had just kept the original frame. The S-10 offers the power steering and independent front suspension, but the width of the track is not wide enough and the body mounts must but modified. If you plan to use the inline six it brings on more issues. he original frame came be modified later if you so choose, there are plenty of sources for after market parts. I would, as other have suggested, just get it going, make it safe to drive and then figure out what you would like to do.
