Preload of the worm bearings is controlled by shims at that lower plate. I know on the later cars the shim pack doubles as the gasket for the plate; the gasket is made of multiple thin plies that one may remove as necessary. 39 I don't know, but the shim may just be a ring of paper or steel that is placed in the end of the housing bore before the cover is installed. They need to have a right fair preload on them that is noticeable when turning the shaft by hand.

Another source of play in high mileage cars is the sector gear moving in the sector as those thrust bearings have worn. That will take some creative disassembly and shimming if that is the case.
