I just thought of something, if you have an anti-deiseling relay in your A/C system, it is used to put a load on the engine by engaging the A/C clutch when you turn off the truck. I'm not sure how exactly those anti-deiseling relays work because that was not yet invented in 1969. It seems to me that would have to be a timer relay, but I don't know that it is. Others on the forum may have a clue.
