Any ideas as to the truth of this or any workarounds?
Those are great cranks, very elegant and classy, beautiful.
Going to say upfront, proceed with caution. In my experience most square tapers will work with each other despite being ISO, JIS, etc. Many disagree on this. They may sit in a different installed position if they are not matching and may rub each other the wrong way depending on stretch, age, wear, fatigue, etc. You might want to seek out a bike co-op for help and guidance. YMMV
