When I first got my truck the original seat was basically a bare frame so I replaced it with a seat from a 66 Dodge Fury III. The seat fit well in the cab and was comfortable but it needed to be recovered and it always bugged me that it didn't tip forward like the original. I was browsing Kijiji looking for a late 80's Chevy truck seat when I stumbled onto this:
It is a stock seat that has been recovered out of a 1959 GMC Grain Truck. I couldn't believe my luck, a stock seat that was recovered in the color I want that will bolt right in
