2005 Sierra CC w/2014 Denali 20" wheels ?
 

Would anyone on the board know if this swap is a bolt on type deal or would it require modifications? Thanks for any help you can offer.
Mike

I should add the 20's currently have 275/55 tires mounted.

Couldn't ask for a more detailed reply than that. Now I know I want those wheels for sure.
Thank you, and that's a great looking truck.
