rooster comb

Have 67 904 transmission with a 1 pin neutral safety switch,want to put the trans.in a 1970 car which is wired for a 3 pin switch,can I take the rooster comb out of 727 that is for the 3 pin style and put it in the 904,thanks

You could just change the whole valve body

A single pin switch grounds the starter relay in neutral and park. A 3 pin switch does the same through the center pin and turns on the reverse lights as it closes the circuit between the 2 outside pins.
