Hi, cranks have different offsets. If you look down at the arm, on the inside were the spindle inserts to the arm and then see the distance out to the chain ring between your 2 cranks you will see the diff. offset between them. That is what you would be trying to match up as well as the bolt circle diameter if you needed the chain ring for proper gearing. In order to use the original bottom bracket, it easier to replace the BB for the crank and be done unless that bike is not a parts bike. Replacing the bottom bracket to match your crank should work or new Crank and BB. The manufacturer is Currie, Good luck
