P.S.: Might as well put my shameless plug in here: I need a pair of NR crankarms. Post '77 preferably. 170-175 OK.

The spindle length was increased by 2.5mm on the drive side, but I can't see the diff on the arms, either. And I think I saw some NR cranks in the for trade section of road bikes. check there.
