Thanks for the replies. I figured they weren't factory but haven't been able to find anything like them (at least not reflective red).
I haven't seen anything on rappy graphics but they're pretty old decals too, so I'll contact them and see what they say.
The graphics on the truck for Northwest Auto Salon look identical but in a silver reflective version so maybe they can help point me in the right direction. Probably from the same place as mine...
I bought this truck a year old from Pittsburgh, PA and the decals were on it then.
