I know i saw a correct template for 66 sd fender gill placement but I cannot find it. Can someone point me in the right direction. Any tips on the project more than appreciated. Thanks

Hopefully this helps-

i am looking but i can`t seem to find the direction for the gills. Do they bring air in or let air out?

A couple of grainy photos from the archives (as my car is currently in storage).  Hope they assist

Think they would be the same distance/angle as an SD Canso ( think Beaumont has 10 louvers) but just a diff location? As I have templates.....   Rounded side forward.....cupped side would slow you down....
