Wanted Old Seitz blind catches top and bottom

Hi all. Yes seems so minor but I can't find a set of catches for one of my blinds to flyscreen on the old 1993 topaz.
I know they were used on other models around that time but it's hard tracking these small things down.
Autosleeper have no such stock.

They slide across the channel and clip into the cut out slots to be aligned.

 Anyone have some? I'll take any assortment of left and right / top and bottom fixing.
Cream in colour ideally.

Any breakers know about to inquire at also would be a help.

I should really be adressing the rust buy hey , it's the little things in life...
