Stick ons are definitely the proper ones. If you look in a parts manual 70 and 71 have different part numbers. Now the good and the bad, bad first good luck trying to find new/nos ones. There are nice used ones out there and although it is a bit tedious double sided tape can be applied and trimmed and they look great, have done it. The 70’s are the same size and profile, you would have to remove the pins and apply the tape. I do believe the location they belong on the fender is right over the fender reinforcement not allowing any pin fasteners therefore the tape/stick on. Hope this helps.
