I have a Harley 16" front wheel. It is a 16 spoke mag with dual discs.
I was told that it came on Big Twins from 1987--1995.
The part number for the speedo drive is 67073-84A.

I need a speedometer--BUT--do I need a 2:1 ratio or a 2240:60 ratio?

Also--the wheel has 2 "washers--spacers" one is flat and the other has a shoulder and is a little thicker.
Do these go under the wheel grease seals or on top of them?
Does it matter which one goes on which side?

Thank you.
