Needed: Nomad/wagon rear seat back brackets!

I just learned that my '57 Nomad 'kit' I purchased apparently did not include the seat back brackets which attach the rear seat back to the inner fender well; I thought they were still attached to the seat back but they aren't and I haven't been able to find them in the boxes of parts!

Attachment 11880

Question: Are these brackets (see photo) the same for all wagons and Nomads? or are Nomads unique? I think they are the same for all wagons! Does anyone have an extra pair they can part with? Let me know via PM if you do... Thanks!

I have a pair

Thanks Carnut, but I've found and bought a pair already! :)
