I strongly suggest that, when replacing the springs, you also replace those impossible to get at screws with 1/4 - 20 machine screws w/the brackets tapped accordingly. If you do that, then you have a nice option of placing shims under the head of the machine screw to correct the inevitable warpage of the rail.
