Rear window trim

[rihavens]

So I replaced my rear window weather stripping. The write up I found said to use a screwdriver and remove the trim on both sides of the window. This promptly broke the trim completely on one side and damaged the other. It looks like it SUPPOSED to slide up. Anyway. I ordered the RH side replacement, but I do not know where to get the plastic clips to hold it in.

Any help would be appreciated. Thanks.
