I can only find some random listings on ebay for 2 pcs, anyone know any websites I can purchase these from? I would love the Bronze pictured below, but maybe those Rotas where powder coated/painted, which I have no problem with doing. The Orange Spice photo is my current setup, I was also looking for the Sparco Terras as backup but I don't think they make those in a 4 x 108.
