I traded for a 1 ton frame a few months ago,it didn't have a body on it but had all the running gear and tc, transmission but no motor. The other day I was going to use the divorced tc on another truck I'm building, so when I went to see what the tc was it had napco on the sticker.I looked it up and found info on napco trucks ,but mine also has a swivel frame by truckstell. I've seen a couple of trucks with the swivel frame, but no one has said anything thing about napco and swivel together. I was wondering if anyone might know what that thing is worth. I didn't have the heart to use the tc,I'm going to restore it. Thanks for any help I can get.
