That is some collection there. I'm jealous. Do you keep them mostly stock?
No, they look stock but aren’t. The Power Wagon body is stock but it has a 360 V8, power steering and front disc brakes, original axles with 4.89 gears.
The Carryall has a stock drive train and axles, but I have some 4.89 gears for it and a synchro NP435 trans that I’m going to eventually install. The body has been modified with the addition of a steel roof; the originals had a large canvas section, and I eliminated the external battery box on the right side. The battery box area was rusted out badly and I rebuilt the area without it. All new 16 gauge steel.
