All great advice. I have Mavic Racer centerpulls on the yellow P13 and they work fine. It sounds like fitting the Campy sidepulls might be a problem, so I think I'll keep the Weinmann centerpulls and put Koolstop pads on them as you suggest (the original owner says the pads currently on both front and rear brakes are original from 1972). The former owner also said the hoods had dried out and disintegrated, so I'll put new ones on today or tomorrow.
So far, I've ridden the bike twice between rainstorms, and it might be my imagination but the looks I've gotten from pedestrians and other cyclists make me feel like I'm driving a pimpmobile.
