Kevin,
A German guy has some wings and other parts for sale.
Go to :
www.a112.de [nofollow]And than click "Markt" and than "Aktuelle Angebote". The fourth advert from above is the one I mean (from Reinhard Lutzweiler).
"Kotflügel r. + l. bis Bj.77: 100 EUR
ditto ab 78: 85 EUR"
Hope this helps,
Alex van de Wetering, The Netherlands
