/6 air cleaner

Hello, I'm looking for an "undesireable" 1 barrel slant six air cleaner assembly. I'm going to cut the side of the top section off and make a custom air cleaner. So, I don't really want a good one. I would like for the very top of the top section to be straight or only slightly bent. Free would be awesome or at least very cheap do to the condition I'm looking for. Shipping being an obvious exclusion to that.
