I looked at kneedraggers for the Galfer kits. There is a kit for 2003 and a kit for 1999-2002. I would make sure your kit is designed for the 03 model. I bet the only difference is probably the lenght of the brake line and maybe the angle of the AN fitting.
Yeah, they changed a lot in '03. Wouldn't be suprised if the lines a different, too. Nothing else is the same.
Also, the '03 has two lines coming off the master cylinder, one for each caliper, and I think that up until 2002, there was only one line coming off of it, with a jumper from one caliper to the other.
