vintage air in 57 chevy
I am getting a vintage air unit for my 57 chevy. I have installed one in a chevelle. In the chevelle we had to do some modifications to the dashboard, i.e. cut holes for air ducts, and was wondering if I'd have to do anything like that to my dashboard? What difficulties might I face with installation? On the Chevelle the hardest part was making the holes, and everything else was a piece of cake. I would expect the same for the 57 but am still curious. Thank you.
