One comment, if you are able to hear it, it is apparently
still working. You may be chasing the wrong solution.
Also, on my '67, I just had to replace my turn signal flasher,
which was NOT reachable without removing the instrument
panel. It was tucked up higher than some, perhaps, but
since my wasn't working at all anymore, I couldn't use the
sound to track it down. While I had it all apart, I took the
opportunity to replace the instrument panel bulbs, which
makes my dash MUCH easier to see at night.
