Summary
Like many, the vents in my FJ80 are loose from the tabs breaking off. In my case, the “pins” on the vents themselves were sheared off, and the small plates that the pins mate with crumbled when I took them out.
I’ve designed a 3D printable part that fits securely into the vent housing, and has a pin that now fits a hole drilled into the vents themselves. Here’s a render for the middle vent. (the side needs a slight offset.) Dimensions in mm.
