Ah, that's pretty cool. Did this cab come from over seas? Are you thinking of scratch building the frame and other components, or did you mean you were just buying all the Tamiya parts separately? If you need an idea, maybe you should make one of the Macks into a pulling truck. I remember when I was 5 or 6 years old - the first truck pull I ever saw had a Mack in it. It's name was Mack Attack.
