Rrc challenge wings

Hi ppl. I have a tray back Range Rover classic got loads to do, getting there spending the monies Lol. I want challenge wings for it but am struggling to find any for sale or anyone who can make them up for me. It's tray backed already so it wouldn't look right to leave it original. Plus I've got a full led kit ready & led front lights all for defender but will fit Hope someone can help
