Re: Flaher for BN1 - Where does it mount?
Since I don't care that much about concours correctness & it can't be seen anyway, I just used a modern flasher unit. Napa #50-263-3, tucked in behind the carpet at the top of the extension panel. Out of sight, easy access, & works well with all bulb combinations. Much better than the load & voltage sensitive original Lucas flasher.
