Very kool Dave, thanks for posting that. I met Ron Fournier years ago when he was building the scale Indy Cars. I did some artwork and photo-etching for those cars. The grilles and suspension links. Very nice guy. He and his wife even drove his hand built hotrod up to the house one time.
The 1st pic in your photos is of the 1/24th scale model that R-M did of those cars, right? They did a couple of different IMSA cars if I remember right.
