I am still trying to decide which gear to put on my 89 GT AOD vert. I keep reading go with a 4.10 for an GT AOD vert, because it's heavy. I understand that. I am worried if a 4.10 will be too much torque! And, I am worried that my gas mileage will take a major dump! I rarely drive this car on a highway over 60 MPH. On the other hand, I am worried that a 3.73 gear won't be a noticeable upgrading from a 3.27 gear. I would really like some suggestions, that might help me make up my mind. Thanks, Howard
