47-55.1 Reverse switch, Lokar shifter

[Livemeyer]

Though I'm pleased I was successfully able to rewire my entire truck, I left one issue to troubleshoot until today: reverse lights. After some head-scratching and consternation, I discovered that a) both the reverse light bulbs were burned out, and that b) the Lokar shifter switch I wired up is really a momentary off, normal on switch, instead of vice-versa, which is what I need.

This switch is at the base of the floor selector and has a ball on one end that gets depressed when in a certain gear. It was difficult to tell if it was reverse or neutral that the switch was being depressed, but I figure if it works in these positions only, I'm okay. Problem is, it cuts power in these positions and stays on when in drive or park. Kinda explains why the bulbs were out!

Anyway, this is a Powerglide transmission and I was hoping I could find the same switch but momentary on while shopping at Lokar's website. They sell a kit that looks like the same switch but mounted at the transmission witch a bracket kit they sell. First, I don't know if it will work with the Powerglide and second I don't know if the switch is the same momentary-off, normal-on type. It wouldn't make much sense for me to order the kit if it does the same thing.

Aside from this, I also am wondering if there's a switch to be found at the transmission for this purpose, in which case I can simply wire to that and not bother with the switch on the Lokar gearshift lever.

Thoughts? Can I modify the switch? Can I get the opposite-style switch?
