Try looking on this site to see if it is the "exact" same part number for each reel. But keep in mind......it does not need to be the exact same part to be interchangeable. Look to see how these 2 parts are made and most likely you can see it the handle will fit.

You can also look on the Shimano web site to get part numbers.
