Sounds like John got a picture.
I have nothing for you, as I buy a car, never sell it. As far as numbers car, build sheet does not matter, anybody then when they were new, modified them, first thing, I did too. I have the same car, color, M21, did not have original engine and was in great shape. Probably paid more than you would ever get for that one, but it was and is the car I wanted. The money you put in them, you never get out of them. More of an adoption to me. Now Family.
Better post to follow.
But some pictures would bring more people.
Same to you John, a picture?
Sounds like a great car and project, glad to have you on board, I only responded because John sounded like he needed some TC.
Sorry, Good Luck on the project.
