I have a chance to buy a 74 k-5 for 300 dollars. The 350 runs fine it has factory roll bar, heavy duty springs brakes, skid plates and gas tank sheild, 203 transfer case, but the tranny only works in reverse. The body is rusted as normal. It would need new fenders, wheel wells, front and rear floors and bedsides. Is 300 a good price or is it way to high for a truck in this shape?
