Greg Boardman is absolutely correct, the Weld wheels on T-Rex engineering are the ONLY wheels I've been able to locate that are the correct offset. Only exception is Rickson's wheels and their aluminum wheels that are coming out sometime for the 2000+ Rams (2000 was the year Dodge started with the extreme offset). Boyd Coddington and a few others get pretty close but still come short by about 1/2" which would be acceptible if you are running flares (not acceptible to me though).
Kent worked his rear off and pestered Weld until they finally committed.
