Well, no luck so far, I am now looking into possibly using the same energy suspension urethane dust boots that go on the HD tie rods. I already have a set that I can check and see if silicone will stick so I can install them, grease them, crank down the nut and hopefully seal them. If not, I'm gonna get crazy and break out the milling machine to mill down into the backside of the balljoint and tap it out to accomodate a zerk fitting so I can at least purge it.
