WTB: cheap 17x8 wheel

[B 4 You]

Hey guys. I'm taking a cross country road trip in a few weeks and I'd like to carry a full size spare with me. I'm looking for a high offset, 17x8 wheel. Must be 5x114.3. I do not care the condition, in fact I'd prefer it to not be good. Surely someone has an old mustang wheel or something laying around and picking up dust. I'm only interested in a single wheel. If you've got one and it's cheap, I wants.
