06 Sonata cabin air filter -how the !@#$ do you get it out?

Trying to change the cabin air filter in my 06 Sonata... three of the
four black plastic clips on the filter frame have all broken off in
the process of trying to pull out the old filter. And the fourth one
is hanging by a thread.

All I did was squeeze them toward each other like the manual said.
Snapped right off.

So, how the heck does this frame come out now that the release clips
(which didn't work anyway) are gone?

Anyone got the part number for a new filter frame. Assuming I ever
get the old one out of course....

Sigh.

Thanks!
