I've contacted a couple people that might have D/Dart cams but had no luck finding one. One member here has a friend that has a similar one but I don't think it is an exact duplicate. The only person that indicated that he had one was Paul Ceasrine. Unfortunately he passed away. He was doing a cam comparison on this site and got to the D/Dart cams and quit. Probably to rattle my chain. I think Paul went by 69 Cuda 440 on this site.
