Rick, as I understand it, if you want something that is not listed you should contact the online store and they'll tell you whether they can supply it. There are way too many parts to create an overall list, so extra bits get added whenever somebody inquires about them. I think the main question will be whether Greenfield still supplies that item to dealers.
When you've done the simple stuff (replacing the worn out parts) if it is still not up to scratch, post some pictures and tell us what is going on. Hopefully we will be able to help.
