Just get another manufactured flat fender hi-line for a little over the quarter the cost of the AEV stuff.
AEV's stuff is premium, the price isn't all that far apart really....
Gen-Right for example, you're looking at almost $900 by the time you get the fenders, inner fender kit and mounting kit. Then you've still some minor fab to do, relocate a bunch of stuff, cut your hood or get the AEV hood, and paint it all. If you go with Rokmen, you save on the parts, but you need to fit & weld everything and still relocate stuff, cut the hood, paint, etc.
The AEV kit is bolt on & trimming mostly.
