Friend of mine got everything for his hydro assist at Northern tool and hardware. Don't know if you have one of those nor do I know what all he got but he told me everything he got off of there shelves and it was a lot cheaper than getting it from a off road shop or web page.
i have looked @ northern tool for qutie a bit of stuff, and found there prices to be high... some stuff they are pretty cheap on, but a lot of the stuff seems way overpriced...
