A good trick is to end every email you send with what you're looking for. Basically every part you could ever want is out there in someone's warehouse, barn, backyard etc.......you just have to make a real effort to find it, a lot of times people hold on to old used parts they don't wanna throw away waiting for just such an instance. When you send someone else a part or buy a part attach your list. Help everyone else you can and don't forget to attach your list. You'll probably find stuff faster than you expect!
