Is there supposed to be a vent cover that snaps into the top of dash to cover these or is this how it is supposed to look? It is a non-AC 1968 GS 400 convertible. What is the part called, a dash vent cover?
I don’t think there is supposed to be a cover there. What you are seeing is a plastic defuser under the dash that is not correctly installed or it has moved. It should lineup better with the dash opening.
