Old Car Repairs Switching motors, I used to stick a large pipe and a hoist into the bumper of my  Power Wagon for lifting motor from vehicles.  Such a handy tool!  Notice the cow in the background, Moo!  Got Milk? A dirty job but someone has to do it! I never rebuilt a motor, I would just find a cheap vehicle with the right motor and use it. All these old Dodges used the same kind of motors. The L head or Flathead 6. Changing front axles on Power Wagons. Dismantling Power Wagons for spare parts. Gotta keep em rolling! Scavenging old trucks for parts Some parts are expensive or hard to find so now and then I would by a vehicle to cannibalize for parts. I'd find an old trucks or cars for a few hundred dollars and dismantle them.  Use what you need, save some parts and sell or trade the rest.  Very little was wasted.  This photo shows a 1941 military Power Wagon that had a 1950's cab added to it.  I had no use for the cab so its going to the scrap yard. save, use or sell almost everything!
