Russell, I like theirs, you can call them and buy it direct from edelbrock, only down side is you will have to wait on hold forever to get some help, i guess they are really busy,
I got right through. But they don't make a 5 piece kit for an 03' GT. In fact, I can't find anyone who does. For some reason, Russel doesn't make the center line, and the guy on tech support had no idea why.
I dont think the new edges have 5 brake lines but I have been wrong plenty times before, lol. I believe they only have 4 they dont use the 1 above the diff that splits to the rear brakes. Which I never understood why they did that to begin with, but hey I guess anything to save a few bucks.
