Yea, I have square taper BB ( I guess, it seems to taper a bit....). I just re greased t he bearings too with white lithium, gonna put the bike back together in the next few days.

edit: I found a pair of newer shimano 600 crank arms (no rings, just the arms). They are 172.5 mm in length instead of 170 however, will I have problems with this? I cant really see the 2mm making a difference (hopefully I dont scrape on the ground while turning....)

Will they fit my current rings? The rings I have are basically perfect condition
