I did order item # 90-063 but it did not fit because the piece that swivels and locks the window sticks out about 5/8" and it needs to be flat.

I'm sorry to hear our 90-063 didn't work. Could you show me a picture of the original lock your window had? Can you also give me its dimensions as compared to our 90-063.
