So, I'm new to the Tons 'o fun group. I just picked up a 1951 GMC 250 dump truck and was told it is a 1 ton so here I am. Was told it ran when parked. Somewhere during it's life it received a 1962 261 chevy engine with the 12v electrical. I gave the fan a push and a pull and it seems to be free. soo now begins the project....along with the 1953 chevy 3/4 ton I've beem slowly bringing back around.
