Nice truck in good condition. I bought one new in 78 and a year later I moved from the east coast to Alaska in it. It hated starting in the real cold weather even with heaters. Other than that I love it. Oh I drove from the east coast to Alaska in five days doing over 80 much of it. I had a CB and truckers would warn me of any smokies.
When you say fine running you mean with the carburetor? Sorry I’m not super knowledgeable, just got a Datsun 620 myself and it runs but revs quite high on 5th gear at 60-55
