This is a resin cab GMC 9500. It is built on modified AMT White Road Boss truck chassis. This was not the good resin cab sold by a reputable dealer on the internet. It was a horrible casting of just a cab from a dishonest resin caster in the southwest that was active in the 1980s. He liked to mix flour with his resin and often did not fill orders. I like the end result of the build, but it was a lot of work.
