I have a '77 Vette with a 350 that needs a new accumulator. A company named Four Seasons sells a replacement; however, it is a new style accumulator. My problem is with the installation. There are only 4 ports to connect on the accumulator, the old (POA style) had 5 ports. I'm looking for a schematic, diagram, or other info I can use in order to make this thing work. It's a hot summer in FL with working A/C!

Thanks guys.
