Hi 71,
It depends exactly what rings you have.
The earlier rings had the clips spot welded to the ring that runs around the perimeter of the trim ring.
The later rings had clips that had the small flanges you see on each side of the clips in your picture. These flanges slid into pockets in the ring that ran around the perimeter.
I believe the clips you show fit rings made after 1975.
If you look closely at the back of your trim rings you'll be able to tell what type you have.
Regards,
Alan
