66 Cuda Neutral safety switch

I don't think that is the correct switch. I do know the coverage years is not what is listed in that ad. and the picture is not correct for 64-65.

You can contact this e-bay seller, I bet he would have the correct switch.

If not I might have one, but would have to look.

I dont know when they changed exactly but I think that switch would work. It looks like the one removed. An earlier switch had 2 wires attached with screws, smaller threads, etc..
The later switch ( 69 maybe ? ) had longer threads and less exposed metal button.
