Desperately need a right roof rail front cover for a Octavia Mk1 Estate

Hi for the last year I have been driving an immaculate one owner 2003 Elegance 110bhp Estate with less than 39000 miles and a full service history. Last week my wife borrowed it for a cross country trip for the first time and came back singing its praises. Unfortunately she also came back minus the front end cap ( I think it’s called the front shell ) for the Right Side Roof rail. I’ve been searching for hours for one online without any luck. I don’t suppose anyone is breaking a mk1 Estate? If not does anyone know if another models front end cap can be modified to fit??

Cheers Stokey
