If I were you, I'd go down to the wreckers with the measurements of your truck cab in hand, and go for some much nicer seats then what were offered in the S10. Quite often wrecker yards get much newer vehicles that were in a bad accident. My buddy just landed a nice set of seats off of a 2009 Buick Rendezvous. Same price as some much more crummy seats that weren't have as nice.
You can also use the rear (bench or captain) seats off of a minivan, that should fit very nicely as well.
