Hey guys I just got a 2004 Ford Ranger 2.3L single cab 5 speed. This being my first truck I need some help on how to make it that much better. I have a simple plan, but i need to do baby steps. Can any one help me with what size brake lines do I need for the front? I ordered pads and rotors and dont want to put them on untill I have stainless steel lines. Any help would be more than appreciated!!

Thanks!
