Try "Bridget768" on eBay. They are around Orlando, FL but I think I recall that they ship internationally. Just bought a left front wing from them, and "Brandi" told me they had 4 X300's and 3 X308's....or vice-versa. Fender listing on ebay carried disclaimer if you don't see it, contact them because all parts not yet listed.
On the other hand...I didn't think about it at the time....was VERY worried what kind of shape the wing would be in after shipping....but if I sat down to imagine a greater shipping nightmare...I think I'd come up with the bumper chrome strip! Good luck. FWIW, my box was pretty well crushed up on one end but the fender was undamaged (in shipping) having a small dent in the wheelwell arch lip, but I think pre-existing.
