I own a 99' 3500 and want to replace the factory wheels with ones from a 02' 3500 Dually so I can safely run 23585R16's. Does anyone know where I can get these from? I called southwestwheel.com and they told me they were all the same. I do not believe them because I have a friend who has a 02' 3500 and his door sticker says 235's and mine says 215's. Any help locating them would be appreciated.
