Guys, want to replace the rubber flex lines to the calipers on all 4 corners. I think I'm running Grand Am calapers on the front. On the rear I believe its the front of a 4wd Blazer calaper. Can you custom order these somewhere? What do I need to figure out for the threads, banjo bolt size etc.... in order to make this work? Can you just get the fittings from Earls???
