Simple Question

[Marlin]

I have searched for the answer to question and can not find a complete answer. Will 18 inch wheels from 2000 or 2001 fit on a 1999? I have found threads that imply they will but are there any changes that need to be made to use them; ie. changes to the speedometer or changes to anything in the drive line?

Yes they fit. There is no difference. The only thing that matters is the outer diameter for the tire. That is the only thing that will change your speedo.
