I thank all for the feedback and interesting peripheral subject matter my post brought to mind. I am not going to put the shield on my car for now, with most evidence that it may not have had it to begin with. (of course, Mr.Speegle could be correct and the inner wheel well could have been replaced, but with 9 28 date code( 10-18 approx. build date) for my outer fenders that have no rust , I am going to guess the inners are original too, they seem to be as such)
Question I would have, if I was to be judged at a show, would the judge know enough to look for evidence of staple holes or rivet holes, see no evidence of that on my car and not mark me down. Or, would they just not see the pad and pretty much figure it is something I just didn't correctly have, when I may have not had one to begin with and deduct some points? (I am not going to invest in the industrial stapler to put this pad on my inner fender since it seems most if not all 66 San Jose cars built in the 65 calendar year seem to have the stapes vs. rivets!)
