Ahem.......
I drive a CMC.
We don’t DO horn Grille rubber-thingies. WE drive “Kit Cars” (notice the caps).
We just shoot a bead of GE Silicon caulk around the hole and smoosh it right on there. Looks more “authentic CMC” if we don’t clean the excess silicon off, too.
All Y’all know I’m kidding, right? They have those rubber thingies at International Mercantile, too, and like the engine grill O-ring above, try to get one that is a continuous O-ring that stretches a little bit, not one that must be glued at the ends once fitted. International Mercantile and others also have the “T” shaped rubber that goes between the headlight trim ring and the body, as well as the rubber base for the front directionals and rear tail lights - both bee hive and tear drops, and the rubber under the door handles, if you need it.
All these details not only make your car more “finished” looking, in general, they get you closer to the look of an original, too. Great winter projects!
