By some crazy chance, does anyone know which (if any) of the vents on this page link are correct for the outer (left/right) vents on a 1975 Maverick with AC? http://www.nostalgicairparts.com/ac/dash-vents-77.php
The "75" has a rectangular vent - Right? If ur supply hose are round u can probably use one of rectangular units. U will just have to get one close to the size of the dash hole. Maybe u'll be lucky and get one u can use w/o any mods. I used the 2.5 round ones on my 73.
Yep rectangular - I'll measure tonight when my son gets home. Just curious if anyone knew the answer off hand...
