Hey everyone, this will my first post so hopefully I give enough/right info. So I have a beach cruiser with a 4 stroke engine attached to it, and I'm trying to replace JUST the crank arms as the thread for the pedal has somehow gotten messed up and it's all wonky so I would like to replace the crank arms but after doing som.digginin on the web I could only find crank sets and not just the arms which is all I'm looking for. If ne one can point me in right direction i would really appreciate it thanks
