Patience, more soaking and some gentle heat from a propane torch may eventually get you there. I soaked and heated the lowers I'm putting on my DB for a month, I'd spray them twice a day and heat was applied gently so as not to jack up the springs. They are off and sandblasted now, for a while I wondered if they'd ever budge! You'll get there, but if you act out of haste you may screw them up. Again patience is your best tool!:thumbsup:
And get some WD40 or other penatrating oil, unless that's what's in the bucket.
