Alenco Patio Door Tab

A handy person from Lincoln says:
I am a maintenance technician for an apartment community. These tabs that I am looking for need to be pulled out in order to remove the sliding glass door panels. These units were produced in 1996 so many of them are falling apart. Is this something that is still available on the market? We currently purchase the stationary door support clip number 80-051 from you now for these doors.

I am a little bit stumped here. I'm not real familiar with this part you're showing us here. As of right now, I can't determine whether or not we offer a substitute, but we'd still like to try and see what we can do. Could we have you send us a photo of the part installed? That may give us more information.
