What were the earliest year Chevy or GMC trucks with a Napco option? I owned a early 55 Chevy 1/2 ton Napco years ago but I don't think I've ever seen more than 1 or 2 other Advanced Design 4x4's.
I would dearly love to have one again but I've got to get a couple of other projects out of the way. '51 GMC 1 ton and '85 Toyota four runner.

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

Be yourself. If you are ever lost, It will be much easier to find yourself if you know who you are!

The Marmon automobile company was struggling in the late 20s (and also won the 1st Indy 500 in 1911!) and brought in Arthur Herrington, a new partner who had extensive experience in military front drive axles to help them find a new direction. They were converting pickups and trucks in the early and mid 30s to 4 WD.
Cole, an approved supplier of front driving axles to GMC, also was around before the war as was Howe who was doing front drive axles conversions in the forties.
NAPCO is perhaps the most recognized by us GM guys, but them Phord guys were in bed with M-H almost 20 years before "us". | | |
