Vent box hinge - 1966 Plymouth Valiant

I didn't realize that they were different on early A's . The one I have is from a 74 so it may not work for you. Sorry about that.
It appears that the hinge pivots are just rivets... take the box off and look at them....do they look like rivets? If so just take them to a machine shop or even a HVAC shop and flutter your big browns...lol.. Or drill them out yourself and clean the metal parts with steel wool , get the pivot points real clean... Then go to hardware store and buy some black epoxy appliance paint. Then off to the fabric store for some thin dense foam..

Voila... you have restored your air boxes !


Some of you metal working guys out there probably know the technical term for those rivets...
