Concerning the polishing, something I didn't mention which some of you probably already heard ,
YOU CAN POLISH TO MUCH !!
Only polish, do not try to remove factory machine marks !!!!
I had to replace a couple of parts because my "extra" polishing through the mechanism out of timing. 🤬 It was my luck that Dave at CGW understood what I had done and had a couple extra parts and sent them to me to correct my over-exuberant polishing.👍
