Ken, I have a 73L with factory vents and a spare solid hood against the wall for you to measure should you choose to do so. I wanted a GT40 look. The problem for me was the light bar located in the wrong spot for a better opening. I even thought of having two bucket motors to eliminate it. Art had tried various designs on his hood taking pics as he went thru the process. Check with him too.
