Looking for GSC Prop Spinner Backer Plate

Looking for an older Kitfox (Model II or III) aluminum backer plate for the prop spinner (the stamped plate that goes between the prop shaft and prop) that the large aluminum spinner attaches to. If you have one please let me know what it is worth to you. This is an original Kitfox kit supplied item for use with the GSC.

Friend of mine just picked up a Model II, he has the spinner (loose) but unfortunately he is unable to locate the backer plate and was hoping someone had one laying around there shop/hanger that they were willing to part with.

For clarification this is a 7" spinner

I backer plate has been located. Thanks everyone and have a Happy Thanksgiving!
