Hi Scott, its there to prevent putting a side load to the bearings, ball bearings don't like side loads. (Unless its angular contact) So length is the critical factor between the two bearings
If that distance is the same on both of your wheels, or measure the length of both spacers. You should be able to use your old spacer.
