getting a vibration buzz
97 automatic, I can feel a buzz with my feet, don`t know if its tires, brakes, bearing or drive train, I know its not engine or accessories, any ideas where to start looking?

If I had to guess, it being a 97, and knowing what I know about how the Torque Tube for that/those year/s 97-2000 is constructed and how the RUBBER COUPLERS that connect the front and rear shafts together, and all the deterioration that I've see with those rubber couplers,,, I would say that you most likely have a bad TT Coupler/s or a bearing/s inside the TT going bad.
Is it worse under heavy acceleration??
I agree with 3saACROWD! Do some experimentation with different driving and conditions.

the buzzing has been there since I bought it 5 years ago, but very faint, now 20k miles later its getting very noticeable, and it hard to find a pattern, some times I feel no change in the buzzing in the gas pedal, no matter what speed.

I have a 99 coupe that also has a vibration but only occurs once I get around 80 mph. I have replaced brake pads, rotors, shocks, swaybars, swaybar bushings, and am getting ready to replace wheels. I'm having to just continue to work through things until I figure out what it is. I would assume that a vette would be smooth well past 100, but once it starts, it becomes a little unnerving. I haven't really thought about the torque tube, so will have that investigated. I plan on getting new tires soon as well in case there is a broken belt in one of the tires. Keep us posted once you determine what it is.

I have a bit of a shimmy in the wheel from 70-80mph. Just had a road force balance done along with a new alignment and suspension inspection. I was told at this point it's likely a torque tube coupler.
