Hey Mags,
Sadly Extreme were taken to court and lost so they no longer trade. However, they are still able to sell a few bits so it might be worth getting in touch with them.. here is a copy of a recent post by Kevin............
Hi, i can still offer many parts and services including fake brake disc kits, H-gate kits, wheel spacers, window kits and various fiberglass parts. For any inquires please PM me
Many Thanks
