Door panel clip repair?

1964 Imperial

Despite being as careful as possible when I removed the door panels, some of the spring clips broke through when I popped them out of the bottom of the door
The panels themselves are in very good shape and I don't want to make new cards for them
But I also don't want to have missing clips (a problem that will only get worse)
I also don't want to use trim screws to hold them
Any simple ways to reinforce the hole in the panel so it will hold the clips tight?
