Carl,

Good tip on turning the rack end for end.  As near as I can tell the rack
and pinion itself seem to be ok.  I will know more once the new tires and
wheels are installed.  Right now I'm running old wire wheels with 20 year
old tires.  Not the best combination for determining quality of the front
end!
