Two questions. If the turn signal will not stay when I engage the lever (it pops right back to center) any idea what the issue is? I have not taken the cover off to check it out yet. My cover has two holes in it from a tag that was riveted on. Can I buy a cover for the turn signal? (anyone have an old one???) Or... should I try to fill the holes and then paint. Body filler? Solder? Thanks for the help!
