I started out using the sharp end of a kid's drawing compass to pry on the rubber. Stuck myself and tore the part a little. Then I used one of my wife's knitting needles. Ah ha! They are pointed but have a polished & smooth round blunt end that worked the rubber without cutting or tearing. I used this old needle to remove a lot of rubber parts. It worked well just pushing, pulling & tucking a little rubber at a time until those snap in rubber protrusions went back thru the metal holes etc. I cleaned up the parts and they snapped back in place EZ with some assistance from the same tool.
