Accent insert installation trouble and help

Hi folks.

I just purchased the Accent inserts and gaskets for the 69/70 Wheels. I am struggling to master a way to install these properly. The inserts actually seem too small for the holes and have a lot of play. Im hoping I didnt miss something? Any tips, tricks, video links would be a huge help. See photo.

Thanks for your help.

I though Don Rush had a video on that. But could not find it.

My original accent tabs barely cleared the hole with tabs sticking straight back. And then I remember crimping the tabs with rubber on the plier jaws to prevent scratching or denting the accents. But the accents and the gaskets were very close to the same size as the hole, and fit very tight once crimped. Yours both look too small.
