I didn't have to resort to the blue flame. The slider block finally came
loose with liberal application of Kroil and 1100-degree-F air from a heat
gun followed by a twist with a pair of vise-grips. Ran a half-inch reamer
through the block. Polished all the corrosion off the sway bar with a
sandpaper strip and eery cloth. Block is 20mm long. Used one block to put
saw marks 20mm apart on each bar arm on both the inside and outside to
serve as guides to settings. I set the bar two notches up (40mm plus saw
kerfs). Cat is much-more neutral now. Front tires are sharing with each
other better with car rolling less. Plate-style LSD is preventing
wheelspin. This has transformed the handling, There is much more overall
grip. I can provoke both understeer and oversteer now. May try one more
notch at next weekend's autocrosses. I did have to put a little more bend
in the endlinks to allow one more notch. They are factory-bent to clear
the DeDion tube.
Took out the lateral drift on the brackets with slit PEX pieces held in
place with hose clamps. Clicky noise is gone.
