The ISIS bb you need only comes in cartridge style. Chat with Nashbar on spindle length.
Nashbar 20% off sale ends today. Thats a pretty good deal on that crankset.
Other critical factor: 1976 is old enough that there were a lot of different bottom bracket threading sizes then. Swiss, French, Italian, Raleigh, and british standard (yes, a lot of Raleighs did not use the british standard, ouch). So depending on what you have, project could be very straight forward, or it could be a non-starter.
