dimensions of Campy and Shimano 8 spd cassettes?Jon(unregistered)

To make a long story short, is there any reason I shouldn't be using an 8 spd Campy cassette with an 8 speed Shimano drivetrain? (Swap meet purchase of 2 wheelsets, 1 good campy, 1 needing some attention Shimano (both are Mavic Cosmics, but use different rear hubs). I though I could swap freehubs, but not a chance. The Campy cassette was included, and I've tried it out, with only a tiny hesitation shifting both directions. It's an older 105 drivetrain, so there's already a touch of hesitation.
Just wonder if I'm asking for serious trouble 20 miles into a ride, or if this is one of those "hmmm, why didn't I think of that" things. Thank for any help. Jon.

This is not a looming disaster, but it may not shift as well as a Shimano cassette. Shimano 8-speed cassettes are spaced at 4.8m cog-cog. Campy 8 is 5.0. This can degraed shifting at both ends of the cassette. Wheels manufacturing makes spacers which can space a Campy cassete to match Shimano. Branford Bike should have them. But, if you are happy with the shifting now, leave it alone. The deraileur should allow for some slop.
