I like having the alt, p/s, a/c and tensioner available anywhere for replacement. These parts are easily sourced, especially if you are broke down on a sunday in the middle of nowhere. Can you say that about the packages from other companies? This is one of my pet peeves with some of the brake packages available too. Its why I got my stuff from Dr. Diff. Having trick a/m stuff blows when you can"t get replacement parts. Just because it looks cool isn"t enough of a selling point for me. Hooray for SDR! Will be ordering when I can swing it.
