Tim -
I have dozens of pics of Unison seats and parts but I don't know how to post them. You could have went to a GM repair parts counter and bought the driver seat only to put in a truck but the seat riser on the passenger side would be kind of funky looking with nothing else there. I'm sure they only came in pairs.
You could certainly modify suburban seats to fit a pickup but they are a totally different animal than the Unisons.
