I have a 69 Shelby with AC. I wanted to know if any one has the page from the shop manual that shows the fitting from the AC hoses from the firewall to the compressor. I thought there was a small check valve inside the top fitting when I took it apart. Not sure if i lost it or what? Or is there a site that I can access to get this detailed cutaway of how this was assembled?

thanks, mark
