kfk, thanks for the reply. I live in a rural area of Georgia (USA) so not much knowledge is available here. My Duck is titled as a 1968 2CV6 Club. I seems to have been updated. It has the LHM disk brakes and a newer dash. The problem is a vibration/shimmy at high speeds. Seems to be front end related. Tried to get the new Firestone tires balanced, but no here can figure out how. My mechanic replaced the knife edges and redid brakes recently. I didn't ask about alignment, but he has been pretty good at telling me to get things done. Tom
