Local sale preferred unless you're willing to pay shipping (200 miles from Seattle) I could travel to PortlandOR, VancouverBC or HoustonTX if someone is interested.
Missing spanner wrenches (I think my alignment/corner balance guys may have forgotten to give these back) but these can be purchased on the interwebz (amazon, etc) for $20-30.
