David, Have you tried to start the motor yet// ??? I wouldnt get all hung up on the questions you have posted/ Those answers are most likely lost to time. Keep in mind what the purpose of the build was..... to demonstrate and prove the friction drive and unique differential. I would clean it up, reassemble in its current state and get it runnable. Its a unique piece , show it off as is!! The car is more valuable and unique as is then with new paint and lipstick! Mike West
