Just wondered if anybody had any suggestions about making a 68 center A/C vent look new again. The vent is chromed metal, with black painted fins. The chromed metal part has what appears to be decayed 34 year old sponge rubber on it, and the remaining sponge rubber seal in the plastic housing is shot! I don't think they repro these, although I have seen similar ones for a 67-68 Camaro in the Ground Up catalog. Will they fit?, or somebody that's done a 68 dash resto, point me in the right direction. Thanxxx!-Al
