"Cowl shake", which is what you describe as occurring, is a problem  that 
has been around since the first open cars went over 35 mph -- a full  
roll cage or conversion to a coupe (or is it "sedan") is the only real  
solution for some cars -- other cars seem to be fine  ...



Bill Stanley has better defined the problem(s).  Like the first poster  I 
have had "wobble" on a '66 convertible and a '65 Corsa coupe when each was  
first purchased.  Both were related to badly worn front end parts to  include 
completely shot wheel bearings on the Corsa.  The '66 convertible  also had 
cowl shake that never went away, but which was exacerbated if the  
alignment, wheel balancing and front end weren't within spec.  And all of  my LM 
cars have had a specific speed range with radial tires where there was a  
transitional roughness you could feel at certain speeds (usually between 50 and  
60 mph).  And the Greenbrier, bless her, has always been smooth with radial  
tires (must be that EM body strength :) ).
