Don,

I have done both the S-10 as well as a custom IFS. the S-10 route is the way to go only if you have an S-10 chassis handy and a front clip handy and you like to tinker and make things fit. The three major down sides is the shape of the S-10 frame's rear kickups leave you with minimal bed depth unless the cab is mounted 8" above the frame, the requirement to run 2" wheel spacers on the front, and the radiator to steering interference issue. If I could do it over I would use a stock frame on the truck or build one from scratch because it has less headaches

If your desire is a simple IFS, there are the pinto derived Mustang 2 units (doesnt work with the I-6), and there are the GM-Metric chassis unit that I developed that uses S-10 or G-body front end components and has worked with most engines
