Thanks for the info TKCR. So if I understand you correctly, you are saying that for a given year model, there were not different frames & foam for different trim levels on the truck.

Since the foam I have doesn't work for 81-87, and doesn't work for the 79 bench, are you suggesting that all I have to do (haha - not so easy to find!) is find a 73-76 bench and it will work? Basically I'm thinking a junkyard bench is cheaper than the cost of returning the heavy, bulky foam and upholstery that I already have.
