Nick, what brand rims are those?
They are a set I picked up at a swap meet for 50 bucks. They looked like they had sat in a barn for 25 years. They had so much oxidation on them. Took me and my dad a full weekend of sanding and polishing them to get them that good looking. The brand itself is "Western Wheels".
They were the older "uni-lug" set-up with the slots for the lug-nuts to fit different bolt patterns. They are not new wheels, so I cannot give you a good place to look for them.
