Don't believe our May 14th built San Jose coupe has any plastic retainers for the molding on the front fender either. Just likely the documents (drawings??) are wrong again
At least for the spring production. Are there dates on the "documents" John. If your using the assembly manual as a guide its on each page most pages were collected from different manuals spotted around the year so they don't all match
Looking through my pictures I found even ones with the lettering with only the forward stud hole - no plastic retainer holes. Of course not allot of pictures taken focusing on this specific detail
Hope this sets your mind at ease and lets you go on to the next challenge
One spring example - Happens to be a Calif Special in this case but did find other non- Special
examples also the same way
