Broken Window parts

Hi Swisco,

We just moved to a new house and do not know the brand of our windows. But, we have a couple windows where the pivot bar is no longer holding the window to the frame. The piece that holds the pivot bar (I think it's called the pivot shoe (one of the images above)) had "530C" on it, which is how we figured out that it's one of your parts.

We saw that the bottom part of the window (the other three images) is broken (it bends away from the window and the screw doesn't seem to hold the window to the pivot bar). We think this needs to be replaced. I was wondering if this was your part and/or if you had any suggestions of whose part that might be. Also, do you know the name of that part? Thank you!
