2001 Model 3500 Rims?

[Midnight]

This has been menshioned before,but i want to be sure that i am correct. The 2000-2001 3500 duallies have a different off-set than did the earlier models. Has any one gone to the 235/86/16 on the earlier models,and changed over to the new rims? If you have, where did you get the rims from the dealer? If so can you give me part#,the dealer i talked with have no idea. Another sourse has told me that the rims are all the same from 94-2002. Thanks in advance for the help.
