I wish the "purchase history" tab would work so I can tell you the sizes you need. I bought all new Grey port assemblies. You will need 5 small, 2 medium, and 2 large ports. If I get it to work I will post the sizes I bought. They fit my 79 H30 perfect. Btw, you are better off buying the complete port assembly over buying just the pieces needed. The individual parts are pretty pricey.
