Rear LCA inserts to avoid crushing?

[TurboTerror21]

Hi,

Wondering if there should be an insert of some sort inside the channel of the rear lower control arms for the rear sway bar bolts?

In my attached photo I've made a spacer from some pipe. Curious if this was present on factory cars? These control arms are repops from eBay so I don't know if they're correct.

Originals had a stamped spacer that was in where the spacer you have.
It picked up both bolts.
The set up you have needs one more spacer for the 2nd bolt.
