The tags were typically removed . They unscrewed leaving only the hole most of the time , they were unceremoniously ripped off leaving the screw and a portion of metal from the torn tag sometimes , and the least common from what I have seen was left in place (maybe slightly moved ) while the fender was attached .On unmolested cars you can sometimes see the witness line of unpainted metal from where the painted tag was slightly moved when Smith installed the fenders. They were in the way many times which is why the variations.
