Hello Tony,

Your truck is just like mine, I have 16" in the rear and front but with different backspaces... Fender widening is not really a big deal, and may be easier on the GMC trucks because of the fender shape.. Mine is done, I have the template if anyone wants to borrow it... It is not a straight shot as you would think. See attached photos.
