Have some Q's looking for some A's

[Kager67]

Hey all! I have some questions about a 64 that a neighbor of mine has. It is a four wheel drive half ton. He originally wanted a grand for it, but I got him down to 700. Now that I have looked it over again, I'm not sure if it's worth that or not. Just about every panel is either dented and or rusted. It is a six banger with a four speed. The cool part of it is that it is a factory 4x4. It also has the factory tach, which I'm not sure if that's common or not, but it looks cool. So, I was wondering what you guys think. Also what was the first year for factory four wheel drive? I appreciate any input.
