I installed this on a 1932 Ford Fiber Glass car for a Hot Rod buddy. I actually got it up under the dash. It was a tight fit but ended up very clean looking. Used 3 vents -round on each side of dash & rectangle in center. Pressures are perfect with 44 degrees output. Perfect size for small cabin area. Youe people are great to deal with, Thanks Steve, Pleasure talking to some who cares about their products and wants it done correctly. Thanks again.
