need replacement aluminum window corners

Dear Sir/Madam,

Please find attached photos of the aluminum window system for which I need replacement corners, as some of these have fractured. The brand name on the window latch is Filco. One leg of these corner braces is held in position with a small screw (pictured). The screw hole is drilled clear through the leg of the corner brace. The other leg is crimped into position. The crimped leg appears to fit into a channel formed in the aluminum frame just over the latches. Are the enclosed photos sufficient for positive identification of the required part, or should I grind out the crimps in order to fully remove the other leg of the broken corner brace?

Thank you for your attention to my query.

Thanks, Tom. I further dismantled the window, extracting the other half of the broken part and machined a new one out of aluminum stock. The dimensions of the part correspond very closely to your parts #95-105 & 95-106. I'll order some of these as soon as I receive a response on another part I inquired about.

Thanks, Tom. Looking forward to your reply. It might be a good thing for you guys to tuck into your hatbands the info I just sent you, as you would be able, in the future, to know which part would be needed immediately for a client reporting Filco as their brand of window.
