Call Bret Luter (Rigmaster on the board) - 919.934.4470. I was over there yesterday and I'm pretty sure he can help you out with the first few items.
For the aftermarket stuff/suspension pieces...contact Bobby Thrash, the owner of Strictly German --
bobby@strictly-german.com. I saw that he was selling some used bilsteins on eBay recently; given the number of parts cars he has at his locations, he can probably find what you're looking for on one of the lots. However, given the nature of suspension parts -- it's probably best to just buy new stuff.
Best, whit
