You can use the old '60s single post switch from a 904 or 727 to provide a ground circuit to a starter relay. .... They are still available from a NAPA store. . ....I've installed quite a few Turbo action shifters and have found that the switches they offer work correctly when mounted against a solid surface, the problems arise when mounted on top of the carpeting,which allows too much flex between the switch and the shifter. .....You do always have to play with the adjustment a little, but I installed 3 in the past year and they all worked, park and neutral .....
