Based on your pic's, it looks like a purty solid truck. If your familar with the 60-66 trucks they have their own rust issues, so double check the obvious areas. The paint job doesn't look like a cheap/quickie job. How long ago was it painted? A bad paint job will start showing signs of problems in about 30 days. If you look real close can you see any sand scratches or shrinkage? Now days a good paint job can cost more than the vehicle is worth! Good luck in your decision.
