that's exactly what I did on my heavy 9. The collar had worn a groove into the cast iron face of the worm housing, so I faced that flat and reassembled everything to measure the gap between the collar and the new face of the housing. Then I made a washer to a smidge less than that thickness. Worked a charm to remove end play from the worm.
