I did my own install. Definitely take your time and with the larger sections, an extra pair of hands will help. I second the idea of using tape to help lay it out/line it up. I used tape to hold mine up as I was doing the job solo.
I would like to have some more stripes on mine, but I just haven't found the look I'm happy with. The duals are way overdone and those who have the wide single looks great and those who have the different side stripes(BOSS/MACH) and hood graphics like Humboldt have look good. My problem is the Vista color and want something not seen often.
WAY:OT: , but won't yours out handle and out run a stock Shelby
