I bought a 21 roadwinder wheel for my 2003 nightrain off of Ebay (brand new) it came with bearings installed, a chrome plate for the right side to cover to cover the rotor holes and bolts. it also came with a thin spacer/washer #43313-98. I bolted the wheel on without using this washer and everything seem to line up fine including the rotor into the caliper...my quandry is where does this spacer/washer go or do I need it at all???

If anyones been here your help/advice would be appreciated

 

Just make sure alignment is good.
A lot of the time parts are included to fit different models, not all parts are needed for all models.

 

I bought the Harley 21" mirror chrome Six Spoke wheel for my 03 FXSTSI. Had the tire mounted & bearings installed by the dealer. Mine came with the same thin spacer & on my bike it was installed on left side (opposite side of rotor). My new HD wheel came with instructions which gave the part number for the spacer & where to install it.
