This 1965-1966 Chevy Impala Bel Air Air Conditioning Center Dash Vent is a reproduction of the original GM part. This is a brand new piece with the mounting hardware to secure it to the interior duct. The vent DOES NOT INCLUDE THE CENTER CHROME DIFFUSER but will require you to use your old diffuser. We are in the process of getting the diffusers reproduced but they are not ready yet. Any used diffusers that we have will have pitting and will need to be re-plated. For an additional cost we can include a used diffuser.
