Anyone with English threading. AKA 1.375" X 24 tpi (threads per inch). For the existing crank, the only issue would be the length of the spindle. But you should be able to measure the existing spindle and get that length.

A Shimano UN55 is the model number. They are dirt cheap even when paying full retail at your local LBS.
