Hey Viper79,
May 2010 I bought a yellow front guard from this seller for my 1976 YZ, and the colour Q314Y is way off, not even close. The photo in the ebay add looks the right colour but is more like dull lemon colour. I onsold it here in Australia, and Aust Post broke it in transit, before it got to the buyer, so I'm thinking the type of plastic could be a bit brittle. The shape looks as close to original, and the finish ( smooth & glossy ) is way better than D.C Plastics, but if only they can get the colour right. I contacted them about the colour and their response was that they were manufactured in Thailand, sent to distributor in England, and the colour pigment is somewhat close to original but can't guarantee an identical colour match.
Not worth it if you are restoring your bike, ok if you just want a front guard that looks something like yellow.
