I really like the look of the black, 51 series Rockcrawler wheels (D-hole style), but everyone tells me that I will have to grind my calipers (04 D.Cab). Anyone have any experience with that? How much do I have to grind? Are there any links out there to show me? Any other cheap, black, steel wheels? I found the wheelers, but i like the d-holes more. Thanks.
