Can you replace the light swittch on a 68 without removing the astro ventilation stuff? The astro vent stuff looks like it is in the way. Thanks

It is easier to remove the Astro vent duct to access the headlight switch from underneath the dash. Another way to do it is to remove the instrument panel and gain access that way which involves a little more work, but is easier to get to the switch.

Thanks for the help
