I also have a 71 vert that has been burried in the back of the shop for over 20 years. It has very little, if any rust at all. I am planning to get it going again soon. I bought it in '79 from the original owner. I know of two 71 verts that were used for parts in the 80's. They would have been easily saved today. Unfortunatly I have no idea what the VINS were.
