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.
This is a great forum with lots of helpful experts. THanks! This is a great way to learn and I appreciate all the input. The frame is a Schwinn Super Le Tour 12.2, which I am told was made by Panasonic -- since it was one of the Japanese-made/Schwinn-approved models. Knowing it is a Panasonic frame made for Schwinn and badged as a Super Le Tour 12.2, does that give a clue to the threading? If you are asking yourself why I am devoting time and money to this bike, the answer is that I bought it brand-new in 1976 with my paper route money -- $200!!! and I have ridden it all these 36 years, including touring, and in many triathlons (during my marathoning and ultra-running days I also enjoyed sprint and olympic distance triathlons, even though my bike and swim times were lousy. I sure had fun). I love this old bike.
