I'd like to trade a Campy Record crank set 170mm 9/16 x 26 threading date code 1973 (3 in a diamond) for the same cranks cranks date code 1978. They can be 170mm or 172.5mm. Mine is pretty nice, only a few small scratches / scuffs. We can each keep our own rings, dust caps and chainring bolts, unless you really want the old ones, then we can trade these as well
