Nice job. Mine was completed about five years ago. I also had a 73 way back then, but always liked the 72.
Vincenthdfan I may be able to help you with the gas tank if you are going to restore the 72. I have a perfect 72 tank except for the gas cap neck. It was damage when my painter cleaned it. I have a 71 beat up tank that I was going take the neck from and transplant it to the 72 tank if interested.
