not easy to find one of the earlier headshoks in a good condition. Mine was completely gone and as it was the very first version (they were even called delta shoks) you could not service it. I got myself another cannondale bike for a good price and used the ultra vork on it for my Delta V. Travel was a bit more but the bike handles better with it then with the dead delta vork.
If I come across something I will let you know
