I've thought about the same project myself, as my "new" 84 4000SQ Winter-Beater (Tm) does not have the heated seats, and my '85 and '86 do, so I'm kindah spoiled. It looks to me like the biggest problem would be running the wiring, tough but not impossible. Pulling the parst out of a wreck would be the way to go, low cost and you get to see how das factory did it, etc. -glen
