It is very possible. I had a vibration on my '72 that appeared at around 60mph, and developed into an outright shaking by 75mph. This happened immediately after all new brakes were installed. It turned out that one of the new drums was out of round - you could see the wobble when it was put on a lathe, but it looked perfectly fine otherwise.
