Re: 68 K20 GMC/Chevy
There is a hole at the top of the left A pillar. I think there is a page in the assembly manual showing the factory setup. Where the dash attaches to the bottom of the pillar there is a round hole punched into one of the brace pieces. I'm guessing if the truck was speced with cab lights the hole in the actual A pillar was punched to give access?
