Need "official" name of missing part --> can anyone Identify?

[HOTEL71]

1981 Yamaha XS650

I have the optional sissy bar as shown
on pictures 2 and 3 they show the bar bolted on
but its missing some kind of spacer.

#1---anyone know the official name of this missing part/spacer
(sissy bar spacer and seat spacer has yielded nothing)
#2--babbots online schematics does not show it either
#3--can anyone identify and help?

Thanks in advance

Try searching McMaster-Carr for "unthreaded spacer."

Is it the one part covering the Bolt
Most likely is a small piece of pipe /tube
Right now I am Listening to Rolling Stones they have a song Paint it Black
hacksaw or cutting off a piece ( 2 x ) perhaps a washer or 2
Grinding and Painting -- Paint it Black

Hi HOTEL,
use a sleeve hacksawn off a length of appropriately sized steel tube or a whole stack of plain steel washers.

I would definitely like to add a supportive sissy bar like that to my '80 Special 2. Is one available that will bolt on? Thanks,

I think I would chop off a say 1/2 or 3/4 inch diameter piece of aluminum bar stock and mount it in the lathe and bore a hole down the center to let it slip over the stud.

Hi Ken,
me too, but first I'd have to buy a lathe. Then a small universal mill. Then I'd have to re-organize my workshop.
My daughter says there's a term for this:- "mission creep"
