I'm replacing the ac system in my 88 k2500. I'm having trouble finding the correct seals for the hose to compressor. The ones that came with it are too thin and one port is cut deeper than the original. Anyone have a part number for correct seals? I bought individual ones from napa but they don't fit. I'm also reusing the original hoses cause the replacements are angled different than oem. One part hits the end of valve cover and the other against the electrical connector for the air injection pump. Thank guys.
