You want a set of 44s from an IH Scout 2. Passenger side drop so you can hook the transfer case to your transmission. I've never done an S10 but have done two Chevy Luvs. One w/ Scout 44s & another w/ K5 running gear! What a blast!
Have fun, it's worth it!

You can also divorce mount a Dana 20 if you don't want to deal with the transmission.
