I meant Ukai of course - I always seem to get the word Araya in my head for some reason. I actually have a Ukai in the garage right now, in fact...
However, back in 1990 my Explosif came out of the box with full XC Pro greaseguard - the shop checked and discovered that this was being done when XC Comp was out of stock to keep dealers supplied with ther orders - so I got very, very lucky I guess back then!
You are right about the Impact not being original spec though - this was something I fitted when the original one died (after about 5 minutes) and were originally available with nice graphics that matched the original simple yellow Velocity stem graphic so looked awesome. Utter piece of garbage as a headset though as came loose multiple times on every ride, and would eventually crack on the allen key pinch bolt...
Still waiting on graphics - it's been very hard to get things matched both colour and size-wise...
