Restoring a 1966 Ford F-350 that was my Grand Fathers

My grand father used this truck as a dump truck. My dad and my grand father put the dump bed on it back in the 1980s and he hauled sand, gravel and dirt – you name it. He hauled it with this truck and it has just got a lot of hard miles on it and it had not been taken care of at all. I just acquired it from my grand mother and I am now in the process of restoring it back to some what like new. I just want to leave it like my grand father would have done it if he still had it. My goal this year is finish this truck and start on another one.
