Non-aero Campy calipers with Campagnolo panto'ed in script on the face of the arms. Do I need to post pics or is the script enough to provide an ID?

Then...the hole for the barrel adjusters isn't threaded and the only adjusters I have in my parts bin that are near Campy with the nice rubber ring around the top, are threaded. Am I missing a sleeve - threaded on the inside, smooth on the outside that is inserted into the hole in the caliper arm, or am I completely off the mark and need to hunt down an elusive and expensive replacement?

Experts por favor?
