Finally ! found some rust in my car "1980 `vert " so.. where can i find the parts?

found some rust.. to be honest it is not that bad..
i could put a flat sheet of metal but i want to look it as oriignal as possible..




the reinforcements in the rear end of the front wing, are those special for the cabrio ?
tried a few sites + ebay.. but no luck..

Have a look on here http://www.etkashop.com/vwcp/Golf-Caddy/Golf-1/ they have a few front end panels.
