Not the plug and play type answer i was hoping for, but good info. Ill check with local slot shop(NJ NOSTALGIA HOBBIES) to see what he has. May go with mrrc gears and use Harrys solution. Might even try an mt1 motor.
Couple of questions, do rev/monogram cars have same issue. How do you turn down wheels to inserts(dont have a lathe).
Thanks Bob E
