I've seen diagrams and aftermarket parts (like the Brothers/Holley part # TSA5600 turn signal assembly with cup) that suggests there was a factory option for turn signals on the column for '54.
It's time to replace the old Signal Stat on my '54 3100, so I'm considering options.
It would be nice to have an integrated turn signal assembly instead of the clamp-on. Has anyone tried installing one of these?
