I recently started a "survivor" restoration (just going thru and fixing all the broken stuff) on a '67 4sp. It is missing the back up light switch and the neutral safety switch and I have discovered that screwed into the transmission casing below the 3rd/4th shifter shaft is what appears to be a Throttle control solenoid switch. I don't even have a Throttle control solenoid on the car. Does anyone else have one? Am I supposed to have a Throttle Control Solenoid on the car? (327, 4sp 2bbl carb) Thanks!
