Yep you probably want something you can remove reasonably easy. Short of buying a box of 100 of some kind of special hardware .. a washer would probably do the trick.

I test threaded a 3/16 PAL nut on the posts, they bite very good and would typically thread right back on the previously cut threads.

I noticed on the OEM delete plates the small locating lugs ARE positioned vertically, so they too would intersect the antenna trimmer cutout .. unless the later years didn't have an antenna trimmer.
