Restoring 87’ Minnie Winnie

I’m looking for a replacement ceiling vent control panel for an ‘87 Coleman air conditioning unit. The one in our RV is in sad shape.  My wife and I are hoping to get on the road this spring.  We bought our Winnie in need of repairs for a good trade. Have done much of the needed work but have some more left to do. Are there any RV recycling yards out there?
