My old cruise control used to develop slack because the clamp thing that
held the sleeve of the actuating cable would slowly slip back on the
cable.  Every once in a while I would re-orient it.

I am seeking one of these CCS100 cruise controls, but am having trouble
finding one.  Several places like advance auto online and pep boys online
advertise them for about $100, but are out of stock.  I hope they are still
making these units?  i do see them on ebay for $150+, but would prefer to
get one from a major vendor for $100.
