Thanks Spanky, I believe this is a 1 ton, with the info u provided' "GS", this Truck has no badges as they have been removed, {sure would like to get some}, and I'll use Truckernixs' info and look at the springs when I get back to Truck. And wouldn't one think that it would be alot of work to change out the drums to accomodate 16" wheels from the original 17" or 18"s????
