I am buying an 01 f-250 crew cab diesel. I am also buying the factory 20" wheels and tires off an 05 f-250. What kind of spacers will I have to buy for these wheels to fit. Has anyone installed this year model wheels on an 01? Is the bolt pattern the same? How thick must the spacer be? If anyone has done this where can I buy the spacers and how much do they run? Any info would be greatly appreciated. I am picking up my truck Sunday and having the wheels shipped Monday so let me know asap if they will fit. Thanks in advance.
