GMC fender badges?

[pritch]

I had to go junkyardin' last weekend to find a part for our bar car, a '00 Suzuki Grand Vitara. At the place that finally had the part, near where the 'Zuki was, there was what was left of a '67-'72 GMC. The poor old thing was just about completely crushed and was at the bottom of a stack of cars. About the only thing I could see was the right side front fender, and it had a 'JIMMY/20' badge on it. I figured it was just a fender off a Jimmy, but the paint seemed as old and original as the rest of the truck. Were any GMC trucks badged as 'Jimmy's'?
