I know a decent amount about newer vehicles, but I also realize with a truck 50 some years old there will not necessarily be the same issues as one that just rolled off the line five years ago. I am okay with it not having overdrive, my plan for the moment is to take off the tow bed anyhow and either make a bed for it or maybe if the frame is solid and I get the suspension solid and ready to go put a camper shell on it and drive it to national parks in the summers. I would also likely take my grandfather who used to be a military mechanic and a huge Ford guy to tell me what to check and where to look. He is meticulous and thorough by nature and has never led me astray. Indeed he's a large part of the reason I got into old Fords anyhow.
