Tim did get back to me and generously shared some photos that I had not seen previously. He confirmed that it is a Model 362 with a 63" cab; standard 362 SFFA bumper; and pointed out a sander box behind the fuel tank that I had not noticed before.

I'm sending his info to the guy who is going to print it, and we'll see how close he can get to the actual details. It will be awhile before I make a lot of progress on it, but this certainly gets me further down the road. So far, the frame is 36" long; I've figured out the twin steering, and have bought three sets of air suspension for the drive axles (and four sets for the trailer axles).

Thank you all very much for your help!
