1978 CHEVY C10 MUD TRUCK 3/4 TON AXLES

I don't know to much about this truck but what I do know is the truck has 14 bolt rearend 350th trans headers, THE ROCKER PANELS ARE RUSTED OUT, PARTS OF THE FENDERS HAVE BEEN CUT OUT TO MAKE ROOM FOR THE 38INCH TIRES, MAINLY THIS TRUCK WOULD BE BETTER SUITED FOR OFFROAD USE, THERE ISNOT TO MANY STOCK PARTS ON THIS TRUCK, WITH THAT BEING SAID I was told this truck had a built transmission, transfer case, front and rear diff and that it had 410 gears front and back I can not verify if any of that is true so the TRUCK IS BEING SOLD AS IS THANKS FOR LOOKING,
