84 F800, Looking for a source for the added bottom step, below the tank

 

Upper pic:

 

Looks like this one mounts different.

 

There's only one pic for an F600/900. Are you sure you have an F series and not a L series?

 

Photo is of a F series.
16A470 is the step for a F series with aux fuel tank, they may have changed the way they mount depending on the year model.
If it's missing most just make brackets to fit and weld on a piece of bar grate to the brackets.

 

Yep... its an F800. I can manufacture the brackets. Anytime i can order something at a reasonable price i will. My time is expensive.
