"No dont do that why do you want to do that stop." Lol. I've had my share of that here too.
Doesn't look bad and I'm sure you have your reasons for wanting to do it. If you're a GM truck guy, your eye goes right to the difference in fender opening shape and that is the only issue IMO but most people won't focus on that. I love my 07 which I got from my dad when he picked up a '15 and I admit, I actually prefer the K2 styling. Hopefully they redesigned the way they mount the bed from 2007 which exposes the mounts to direct road filth and rusts them solid.
