need your opinion on this 68 car

Car looks good. My dart was undercoated so yes it is normal. Looks like you need to rebuild the front end. That upper ball joint looks worse for wear. Also I would look at changing those front brake hoses. other then that looks like a good car. One question. Where is your voltage regulator mounted? if I were you I would change the charging system to a one wire alternator. Just food for thought.
