Coleman Roof AC vent repair

Made left and right piece to work with old Coleman Roof AC vents that broke. Mine is from 90's Coleman. Picture its red just left it that color for now so you can see where they go. Common for them to break or get loose so vents just flop around these glue in there so nothing special but sure is nice to have vents that work like new again. If yours are just loose can just leave it but put this behind it for more support to tighten them up.
