I built my jeep as most typical Vietnam War variant. Academy kit needed some small corrections to make it accurate M151A1 and also some extra changes to make it look like early M151A1, most common in Nam. I added gunner's seat and scratch built new machine gun pedestal. I replaced kit M60 gun with Dragon part enhanced with phtotetched parts. I used Eduard set to add these and other smal details.
My review of the Academy kit is here: m151a1-review. Old article from "Workbench" section, where I described some of construction steps, is still available >here<.
