I had a similiar problem with a 78B and my current 70B at 55mph. I balanced
the wheels several times and actually switched wheels from the 78B to the
70B and vice versa. Finally I broke down and purchased new Goodyear tires
for the 70B. Bingo! Shakes went bye bye. Wish I still had the 78B to see
if it would have cured its shakes. As it turned out both cars had 6 years
or older tires on them. They sat still for 3 months in the winter before
being run so they must have developed the out of roundness syndrome (-:
