Morning, my Western Star is the Italari kit, 1/25 scale, truck has square hood and tall ground clearence, used to drive interstate and always loved the lines, very angular and tough looking. Leaving sleeper box off, filling in large hole in back of cab and making it just a window. The forward bunk comes from the AMT release of a logging trailer, that kit has the rack, fwd bunk, pintle hitch, and tractor frame enhancement , pup will mostly be OOB. My tractor wil eventually have an interior, ie seat belts, window visors, switches, de froster vents, maybe even a hardwood floor. I'm mostly an armor/aircraft builder ( collector LOL ) and tend to build very slow however its a fun distraction. May ask for more info on purchasing one of those Mack kits, I have never seen one like that here in the states.
