  1. Cooling Systems, Radiators, Fans / A/C
    I plan to install vintage air dash ducts in my PAINTED & FINISHED 57 Nomad dash....They require 2 1/2" holes drilled into the dash...any advice on this install..I don't want to screw this up....I have a hole saw with a longer 1/4" drill bit ready to go...Thanks :)
