This set  works out slightly cheaper than buying the parts individually. It consists of the following items which can also be bought individually:
1 set of Norton Girder Fork Spindles
1 set of Norton Fork Spindle Nuts
1 set of Norton Fork Knurled Washers
 
Please Note: This set fit all Norton forks except those fitted to the Internationals. These had parallel forks with different bottom spindles. We sell these spindles as well so take a look at our other items if they are what you need.
