Go to the HID here for a parts list.

Some of these part numbers are out of date and the prices aren't correct but the McMaster Carr web page is real good about giving alternatives. I love the one I built. Instead of popping part way out it comes all the way apart when disconnected which makes tire removal real easy. I drive with it disconnected most of the time and have no problems with is being entirely seperated from the center (spindle line). For the price its deffinitly worth it.
