S-10 is really, really narrow. You have to run 2" spacers on an AD, and the TF is about 5" wider yet.
The 73-87 IFS would need to be widened just a bit (or your frame pinched)
I would look into a Corvette IFS and IRS or a Jag unit before spending $3000 on an IFS kit. I also bet that IFS kit is Pinto based as well.
