Question about wheel change

[Alexb00]

Hello I recently replaced all the idler wheels and after completing the job I found this spacer? Would anyone know off the top of their head where it goes?

That spacer looks like the spacer that goes between the inner frame and rear upper large wheels on your suspension. It slides on your upper rear out bound shaft. there is one on each side.

Its been awhile since i had that skid apart but looks like the bushing that goes on the lower Relay Rod Assembly. Those are the 2 aluminum bars that parallel and support the rear shock. Look at the lower bracket that holds it together. I believe there are 2 bushings on each side.
Part no below.
Its #45 on the Parts Catalogue image.
