Campagnolo brake drop bolt: incompatible?


Well, I was OK with the rear brake being a wee bit short; I knew drop bolts existed. So, I ordered one from a parts seller (NOT eBay), the price was OK and "near mint". It arrived last night and i just started assembly of the brake and ? Brake arms won't go on. The micrometer says shaft is 6.04mm, hole in brake arms 5.95mm. Yeah, "Campagnolo compatible" no markings. Anyone run into this? Perhaps later brakes than the Record used a different diameter, and this bolt is for that? Goes to show, "universal application" is relative; perhaps it fits Dura-Ace brakes?

Tempted to bore out the brake arms but I presume I'd never get it right.
