Installed rubber hood to radiator seal but clips keep popping out

I got the correct clips with the seal but they pop out of the hole. The push fastener above was a possible alternative.
I had to hit the clips in with a hammer to seat them properly, and even after seating they popped out.
I got the seal from Classic Ind. and included the clips.

Then find out what size hole those clips are supposed to have and drill yours out a little if they are too small...
