My father has a 1966 coupe that does a lot of "wandering" as you drive it. In other words, you are constantly turning the wheel back and forth to keep the car going straight. The car had a frame off resto so almost everything is new or rebuilt. My local mechanic said that the steering gear box needed to be rebuilt, so we did that and it is no better. It does not have power steering. Is it the "nature" of these old vettes to drive like that? If so, it is no fun to drive & he is going to sell it. Any advice would be appreciated. Thanks, Jerry.
