Gen 2 rocker assembly?

Was putting on my my non stock rocker assembly onto a new set I bought and I realized. There is nothen between the
Springs on the shafts and the alum stands...
There is to be something there correct? And where can I buy them?

Thin spring shim fills the void.

Mancini, 440 Source, Marsh Performance. They are used on wedges so everyone has them.

edit: They go between the rocker and the shaft.

Being the rockers are machined flat on ends where the spring is not. I would thought they would went between the spring and stands sp the end of spring would not eat into the softer alum stands?

I've always thought that there wouldn't be a downside to having one between the spring and the stand but that's not the way it's done.

I will have to order some
