Pick your part is the a chain of local junk yards. Memeorial day weekend they have a half of sale. So if there's some random part you've been meaning to get this would be the best time to do it. I usally see about half a dozen 4th gens and atleast a couple of 5th gens. Take a look around and unleash your inner MacGuyver.
