WANTED - Narrow-Framed Sliding ScreenDoor Frame or Info

I'm looking for a replacement sliding screen door frame for my Eichler that has a 1" or 1 1/4" frame. The size I need in 81 1/4" x 37".

I've looked into getting a custom frame built, but the narrowest frame width I've been able to find is 1 3/4" and this is not preferable as my slideing door is original and the center frame width is only 1".

Might anyone have one of these laying around I could purchase? Or might any of you fellow Eichler homeowner have info as to where I might turn for such a sliding screen door frame?

Any and all help, information and/or leads would be much appreciated.
