I have a ICT Billet set-up in my Arntz. They had one of the few bracket set-ups that allowed me to locate the alternator to the lower left of the engine so it would not hit the hood.
I think I have a whopping $250 in the whole bracket set-up? That was a few brackets, belt, and adjustable idler. I cleaned them p a little and did some polishing, but nothing major.
