This is the guy at CVA- BPI Customer Service you'll need to talk to. I've included all of his contact info. E-mail him and tell him what you have and he will mail you back with a parts sheet with price list and order form. It took me about a week to ten days from the time the order was submitted til I received my replacement parts.
