the defrost vents on my 82 pickup are brittle as can be and are no longer connected to the dash. I can't seem to find replacement parts anywhere. ebay doesn't have anything and the pull-a-part near me doesn't have any old toyotas . does anyone have any recommendations of where I can check?

 

Here is a passenger side vent:

that's one at least, but the driver's side is in worse condition. maybe I can use an intact one to fabricate the other side
