81 Rear wheel spacer

[Wilcoy02]

We are working on an 81 wing. We took the rear tire and wheel off.
Putting it back on I believe we are missing a spacer between the caliper bracket and swing arm.. We cleaned the entire room and no spacer found.
Looking at the part manual for this bike there is no spacer in the book. Hence no part number.

Looking at the "how to's" and remove rear wheel I find one pic. 13. Place the outer axle spacer in between the caliper bracket and the swingarm

Does the 81 have a spacer? If so can you give me a part number or a diagram of the rear wheel showing it?

Does any one have an extra one laying around? If can not find I am tempted to use washers to fill the space.

any hints???

Honda part number 42312-463-000. That part is used on 80 and 81 Goldwings. It's really just a thick flat washer by the look of it.
