1980 WR 390 Shock Mount Question

I found a set of Remote Ohlins for my bike. The parts manual shows a stepped adapter behind the upper spherical bearing where the shock mounts to the frame. I have the adapter for behind the bearing but none for the front side.
The parts manual does not show an outer one, only the bolt and a washer but it would make sense to me that there should be an adapter on both sides of the bearing?

You mean the adapter with the o ring? There should be one on each side inner and outer.

That's what I mean. Thanks visiteur

Thanks not shown in the parts book. I only have the back (Inside ones). This is what I figured should be there.

parts for Ohlins
no problem

Where are they available? I see them on the various parts sites but looking for a decent price. I can have a buddy machine the two bushings I am missing but probably not worth it. I'm adding a small lathe/mill to my shop wish list!
