Nice work on fitting the model 63 extractor! The ratchet surfaces are so tiny to file and this really adds to the difficulty. I have experience working on my 63 no dash. When I originally purchased it used, it was out of carry up and the cylinder had tons of rotational play. First I installed an oversize cylinder stop and then a new hand that was wider and went to work equalizing the ratchet surfaces with my barrette file. Working off and on for days I finally got it right but it definately wasn't easy. One more thing that wasn't mentioned was the need to have and use a .22 caliber range rod to make sure the barrel cylinder alignment is correct. This definately should be done after any ratchet or cylinder stop work.
