I am going crazy trying to figure out where the back-up light switch is for a 4-speed floor mounted Hurst shifter with a Muncie transmission. I have replaced my original Hurst 4-Speed shifter with an aftermarket Hurst 4-speed. Suppposed to be fully compatible but I see it is not. The aftermarket has a add-in plate for a reverse switch. Original I can't figure out where the darn switch is. Presently the backup lights are on all the time when the car is running. Hopefully someone can steer me in the right direction as to how to get this to all work. I am going to get the original Hurst shifter rebuilt but in the mean time how do I get legal? Thanks, John
