You did all the mods on your ride right? I can't see why you can't do this. Shop will charge at least $800 for the installation. Spread the work over a weekend and take your time. Keep the "Measure twice and cut one" mentality in mind while doing it. You can get it done. I know you're dealing with an expensive piece, it maybe intimating if messes up, but really what's there to mess up if you follow the instructions.
