Welcome to the Stovebolt!
You need the cowl and doors also to make this work. Think of it this way. Cut the cowl free from the COE through the floor just in front of the seat and through the windshield and then graft those parts to the panel or Suburban.
I'm working on a project combining just those parts. I have a '50 COE, a '51 1-ton panel and a '53 Suburban plus pieces of two 1/2-ton panels I'm using as donors on this project.
Where in the Pacific Northwest are you? If you proceed on this project we should get together and compare.
