Early non-aero Dia-Compe Gran Compe levers used gum hoods nearly identical to that of Campagnolo's, save for the Gran Compe lettering on the side. I have a pair on my Victory levers on my '81 Trek 610, and I'm happy to say they're a perfect fit, and you can't tell the difference from a foot (or in some cases, even less) away. The gum material is also much sturdier then the Campagnolo hoods - more likely to last longer under moderate use.
