Thanks, Gordy. I appreciate it. Iâ??ve been off the list a while as family life
kind of got in the way of the Healey. Finally, I get back to the point where
Iâ??m uncovering it and have at least a sketch of a game plan for getting it
back on the road.
37718 is my car number, and my heritage certificate says it was built on April
1, 1957. My number is 214-471-2912. Iâ??ll shoot you a text in a second.
