Doesn't exactly match what I see on your site, but I could drill to fit what you suggest as closest. Tang sticks out 5/8", is 3/16" x 5/16". Does not slide out, too tight a fit to get out; broke one off trying to. May have to leave old ones inside frame.
May be from 2004 Twin Seal window; that's who made the sliding glass door in the modular unit.

Our 26-366 pivot bar might work for you. I know it doesn't have the "T" shaped end, but I think it will still fit into your old pivot shoe. Look it over and see what you think.
