These clips bust in pieces when I try to remove them. and no store carries them, do you have them and do you have a store I can walk into.

I don't believe your clip is still available. You could possibly install something like our 70-145 angle clip on each side with the 33-085 screw. Could that work for you? To be honest, you might want to contact a contractor in your area who has installed this type window and see if they have come up with a solution for this kind of clip.
