Mk1 TT Convertible rear quarter panel change

[RedAndy]

hello all, I;ve got my eye on a cheap TT convertible that has gone in to a hedge backwards and damaged the nearside rear quarter panel quite badly. There's no obvious chassis damage or wheel/suspension damage. I'll have it jigged before I buy, but I dont think the panel will beat out or fill - it'll need replaceing. Does it simply unbolt, or is it a structural part of the chassis that only comes off with a grinder?!

cheers
