Re:
Here are the promised pics. They are really clean, very few marks and 175mm arms. Pictured with original chain ring bolts and a set of sugino rings which I believe are original and have very little wear (46/36/26). I have a new set of sugino rings in 44/34/24 as well, not sure if you want rings or not).
If you are after any other xc pro parts, I have a small stash, including shifters, pedals, hubs, cassettes, mechs and cables.
