here's four
Ok here's four pictures. The inserts the bolts go into pulled out of there holes a little when I bolted on the sprocket. Is cush or not is cush that is the question?

I've never seen a setup quite like that. Are the bolts original, or have they been replaced? Perhaps they're a little too long, which would explain the lifting when the bolts are tightened.
If you were to lock a pair of Vise Grips onto a bolt, can you wiggle it to see if there is a rubber bushing behind it?

Cush or not, it looks like the inserts should be shimmed so that they can bear the surface of the sprocket. It makes no sense (to me) to have a gap between the sprocket and the insert. I'd use some hardened washers of the correct thickness, although they wouldn't have to be hardened. Correct thickness is more important.

What is the ID and the bolt circle of the existing sprocket?

The back of the sprocket is machined with a grove for the pins from my other wheel not the inserts. There will be a gap where the insert meets the sprocket. The machined groove is for holding the pins to stop them from turning when tightened. The inserts just sit on the grove not in it.

It's tough for me to visualize it perfectly, so shim it if you feel it is worthwhile. If you can tap the inserts in without too much effort and you can measure the resulting space between the sprocket and the inserts, a shim might be wise. Shims would help to spread the load outward, rather than all of the load being placed on the center surface. Do you have the rear sprocket ID and bolt circle measurements?
