Hey Mr Duece, the noise is the main reason I do not want a locker. I have been a rodder all my life and it seems the little lady is getting a tad bit nervous as she ages gracefully, so comfort for her and all out HP for me is the theme for the car. I have seen your pictures here on Club Hotrod several times before, those are nice cars, and they must love you at the Chevrolet dealers, buying 2 430's. I think Monday I will send off to Summit and order the Trutrac. I appreciate what ya'll have had to say.
