Yes, there are normally shims between the pinion bearing and the cover plate.

The shims adjust the bearing free-play/pre-load ( steering column "push-pull" ).

The "thrust block" (don't think that's the correct name. -You call it the "damper plunger"?) and small spring push the rack into mesh with the pinion, as well as reducing the effects of play in the rack bearing.
-My early '60 Mk1 had shims between the thrust block and cover plate, (the Somerford Mini picture shows what looks like an O ring, but I think it's a shim, because there is a gasket there as well...).
-That was the last rack I rebuilt.

The spring stops any rattling noise.
