Two good alternatives are Phil Wood cartridges and Sugino Mighty bb's. Campy NR/SR cranks have a different taper and thus need a different spindle from Japanese and newer Campagnolo product. In your area, Montrose Bike Shop would be a good store to go to for the Sugino bracket--the family that owns it also owns a wholesale company known for supplying older and out-of-production parts. Almost any bike store can order Phil Wood products.
