If you are interested, its a online company called Extreme Customs. Clic on wheels, then specify 5 on 4 bolt patern, and the above mentioned wheel will show up.
Edit i think i saw the gray boyds at either summit or jegs, dont remember the price. Same technique at summit, go to wheels, and specify 5 on 4 to see their selection. Wheels for Less is also a good resource, they ship free and include lugs with wheel purchase.
