Thanks for posting all this Don. I have been following your project with a lot of interest.
I wonder how long JD has been making the stronger boot springs ? We tend to go through them pretty fast, we drop 11-52 starter fertilizer in the seed row with the wheat, The fertilizer rusts the boot springs and they break every 2-3 years.
The boot support brackets we built to compensate for worn boot mounting holes and bolts, also forces the boots against the discs to keep good contact and prevent the build up of wet straw and mud between the boot and disc.

Our boot support brackets hold the boot in the correct position in spite of worn holes and bolts. We also had problems with wet straw building up between the boot and disc, so we built the jacker bolts on the brackets to serve a dual purpose, they not only hold the rear of the boot in the correct position on the disc, they also contact the boot at an angle so they wedge the boot against the discs. This eliminated the wet mud and straw buildup on the boots.
This wedging action is so effective that there is no difference in performance of a opener with a broken spring. We never know a spring is broken until we find them rattling loose during service.

You will notice in my pictures, that the "jacker bolt" that allows adjustment for making the bracket work with the boot in any of the 3 mounting holes, leans to the disc side so the bolt head wedges the boot against the disc.
