BJ, for what it's worth, here are the switches I'm using....
I think they were around $12-$14 each (bought them a number of years ago).
One thing that makes them look more original is the countersunk straight slotted head screws. If you wanted to add them to your install for appearance, I have boxes full of them. Let me know if you need any freebies....we Aus. FIA guys need to stick together
Cheers,
Glen
