Welcome PKelly form North Carolina
, I know it is special to have grandfather and dads old truck. I'm sure it would bring back some good memories. I would suggest that if you had time go take a class at a nearby Community College in automotive body repair. Spend 8 to 12 weeks learning from a pro and then take that knowage and put on the truck. Grandfather would be PROUD. Also motor work is not all that hard, if your going to go back mostly stock then it's not as difficult as putting a big horsepower motor
together. We have a place here in North Carolina called CLASSIC MUSCLE
