Hi. I'm new here, and thought I'd posted yesterday to inquire about swapping a crank from 90's Peugeot road bike to an old (I'm guessing late 70's) Fontan women's road bike. Have attached pic here for what it's worth. Question is, having tried two crank removal tools and failed both times (too small) am I in any case going to need to swap out cups and spindle/axle?

Thanks for any advice!
