I know where a '73 is sitting in the woods that a guy wants to get rid off that I am a little interested in. It has no motor or tranny and has rust in the typical places, but I seen some rot in the door jam next to the hinges. The door doesn't want to open or close very well. Should I buy this K5 or pass. I know that it is the only year of this body style. Or is it too much trouble?
