I am currently in the process of restoring an 88 vert and focusing on the interior. The plastic clips which attach the inner pivoting vent louvre assembly to the outer frame are broken. I have a picture below to show what I’m referencing. Are there aftermarket clips available that can be glued/epoxied back on to the original vent? I’m trying to avoid buying used ones as these are in great shape outside of the broken clips. Thanks.
