Only just seen that no-one replied to your message.
I think new Raid plastics are just about unobtainable now - unless someone can correct me - although front and rear mudguards are the same as the OE and might be easier to find. Maybe fire a WhatsApp or email off to Steve at Totally TTRs to ask whether he has anything available?
D&D Graphics used to sell Raid graphics IIRC although they aren't shown on the website. It might be worth emailing Karl Barker to ask if he can help.
