I'm firing up my torch Martin.

My vote is keep it stock as much as you can. While these trucks are not "rare", if you look most have been hotrodded. You are also preserving a bit of history. IMHO part of the charm of driving my old '38 is experiencing it the way it was back then. The whining straight cut gears, the rough ride, the non power brakes, the leaking oil, it's just freeking fun. If I want comfort I get in my modern truck or car.
