Dear Stan
I come too far and with your, GRJ and others help me to make my dream a reality to stop now. So I purchased the Aoshima with led scanner at 1:43 scale. The only way to make the Hot wheels car work is in a machine shop. I would need use of a milling machine and cut off one lay at a time from the inside of the car to make the led slot. This is time consuming, I do not have a milling machine and the possibility of damaging the car runs high. Once I get the new Knight Rider I will let you know.
