I noticed that the tail light housings on my 67 are missing all but one of these plugs. Not sure what they are for and where I can get some. I've seen them in lots of pictures tail lights, but no one seems to have inquired about them on the forums. Any idea for a source ? maybe just some cigarette butts (unused)? Please advise, Chris
Note: I stole the picture from them web and circled the parts of concern.....
