Looking for N/S front wing

Hi taken the front end apart to clean, smooth and respray etc just a general tinker (as you do) found rust holes on the wing and need a replacement either a rust free original or if anyone knows of anywhere I can buy a decent new one for under 100 then please let me know where and what sort of quality they are! The car is a late clipper gti model I know the shapes vary.
Also looking for a rain tray / skuttle panel as mine is dying and it's letting the bay down
Sorry if this is in the wrong section of the forum.
Thanks for reading, slowly getting somewhere with it i live in congleton but will travel to collect parts cheers
