Where are you located? Most of us put that in some form in the User CP data. And try a WTB (Wanted To Buy) or ISO (In Search Of) in C&V Sales suggested previously.

Is there a bike co-op in your area, or a used bike emporium? Either would be a great source for a crankset that would meet your needs.

Probably no need to replace the existing BB spindle unless it’s no longer spinning smoothly. As noted earlier, that 119mm length works on a variety of earlier cranksets. Seems like only newer cranks use the shorter BB.
