1970 dart swinger front and rear window trim

I am restoring a 1970 dodge dart swinger been having a hard time getting the corners of the window trim to stay in place. Keeps popping out of the clips. I bought a new set of trim clips and installed them. There were some wider clips in there and regular size clips. Do the wider clips go in the corners? How can I fix this problem haha. Thanks any advice would be greatly appreciated! Thanks!
