Brian, hopefully someone can help you out with measurements of the air cleaner (sorry, I am months away from my car and disappointed also that I don't have pictures already! Here are some pictures of the air cleaner, the air filter is a Napa Gold 2063---a cross reference shows it used on just about every Ford since the late 50's (including all Mustang, so starting with a low-profile air cleaner for a Mustang may not be a had start). The air tubes turn 90' and go thru the cast aluminum piece on either side--there is no clamp at the air cleaner, at the "aluminum" end the tubes just slip fit to the insides. These pictures of the hangers may help https://pantera.infopop.cc/top...r-paper-tube-hangers
(hmm, if someone would make a paper template of the air horns and scan it...)
