Title says it. I *can* fabricate one, just hoping there's a cheap alternative out there. I'll do a proper cowl vent repair next summer.
There was a guy on ebay that made them for Mavericks/Comets. They were like a giant refrigerator magnet.
I used magnetic material that sign businesses use. Easy to cut and last a while. Cheap too. Most sign shops have scraps of it laying around.
Lowes carries the magnetic HVAC covers. 3 to a pack and easy to trim. Working great so far. Thanks for the idea, my fabrication would have been massively over-engineered.
