is there a complete pad kit for it. I see some from Sonus and a couple others, but they say perfectly balanced for the PC7424 and I know it has a smaller pad and weight. Is there a kit for the 7336 that I can just click on and order, or will I have to buy things seperate? Something about a backing plate??? I have never seen a kit that says for the PC7336 w/ 6" pad..??? Maybe I'm just over looking it.
