My TBS seems to be stuck in closed circuit and I can’t seem to fix it.   It also appears that this is an NLA (and quite pricey) part.  Does anyone have a good used one they can part with?

I have an 83.5 and this looks like the switch I have though I’m not 100% sure.  It’s listed for use with an ‘84.  This is what it looks like.

Thanks,
Bryan
