Hey all , I am in the process of changing gears from 3.73 to 4.30 and I came across an add on craigslist with a guy that sells new ford axles. He has one with 4.30 and LS complete with rotors my question is what do I need to look for so that the speedo and the abs works. Its a f350 axle and its going into a 2003 f250. Thanks for the help
