Advice needed

[GMCRepair]

I have the opportunity to acquire two trucks from my father in law.

One is a 67 Chevrolet half ton with a 283 (from what I was told) with a 4 speed manual.

I have with my wife since 2001, and I have never seen this one run or move under its own power.

The other is a 71 GMC half ton with a 350 and an auto transmission. This one I have seen running and driven, but it was more than a decade ago. there are cancer spot on the cab, the bottom of the bed is shot, the dash pad is shot and I know it will need a new seat. It is mechanically stock and complete.

I need some realistic advice as to what to look for in these trucks to see if they are remotely salvageable.

I havent made up my mind as to if I am going to take them yet,

I don't have pictures yet, just looking for some advice.
