I've lowered it and I'll apply the grease and put the rubber shim under the rear bracket as you showed on the illustration.

Lowering it may be all you have to do. I hadn't figured that you may have had it too high, but that would contribute to squeaking at the spring nuts. B67's work best when they are a tad lower than you might set a road saddle - maybe a centimeter lower. This gives a little more room for your thigh at the back, where it meets the flair. Also, before you grease, tighten the nuts a little. You'll be surprised at how loose they are. Not too tight, just re-snug them with a 13mm wrench. And remember to just squeeze the skirts together to test for the leather-on-steel rubbing before you bother with the rubber gaskets.
