Maxxair Vent cover install on OEM vent
I am trying to install one of these Maxxair Vent covers on my 81. The OEM vent has round corners and the mounting brackets don't have any place to go if I use the mounting holes in the vent flange. I guess I am going to have to mount the brackets farther inboard where they will be on the flat portion of the vent housing. I could just drill new holes in the plastic flange (cracks) or make a bar that spans the reinforced mounting points. I was wondering if anyone had done something similar and how that worked.
