I am about to swap my IRS with a guy that has an 04' Mach. I know that our brake calipers & everything are the same, so they will just swap over, but the shop doing his install said that we need to swap brake lines. Everything I have read has found this to be untrue, but I just want to confirm this cause I really don't want to disconnect my brake lines if I don't have to but don't want to hold up his install. So hopefully somebody that has made this swap with a Mach can confirm this for me. Thanks for anybodys help!
