I have a source for shock discs

[Darryl Coit]

I recently had some very nice shock discs made by a local commercial gasket company. They are made out of neoprene rubber and look great. They were cut using a CNC water jet and are made exactly to the Porterfield drawing. I chose a shore A value of 60 for my discs but I haven't tried them yet since my CP65 project is not quite finished. They may be a little stiff. They can make them in any hardness that you want. They are not a PMA part of course but you can have them made under your supervision by providing the maker with specifications from the original Porterfield drawing and then declaring that they are owner made parts. Email me at [e-mail] for more info. Thanks Darryl Coit, Joplin, Mo.
