How different is the Colorado/Canyon front fender from that of a TB or Envoy? I realize the rear wouldn't work at all, but if the front is similar then the Bushwacker set could be used up front.
There is also a post on Trailvoy about the jeep style being something that was close but not quite. If your going to cut the fender anyways does it matter? I posted there about how close the front was to fitting from the jeep, but only got refered to this site for this post.
I've checked with our local salvage yard for both a Colorado or Cherokee fender flare set but had no luck to see how they would compare to that of a TB. From the install pdf on the cut outs for the Cherokee, it would take some modification of the Bushwacker flares to make them work, which may be moot if the fender opening isn't close.
I don't get to town often with the TB to be able to pull up next to another vehicle to compare wheel openings to see if there is any chance of having another platform part work.
Myself, I would prefer the pocket cutout style, atleast for the front and the matching "look" for the rear, maybe with the option of opening up the fender and getting adjustable arms for the rear to clear larger tires later on.
