Torque converter to flexplate balanced?

    I have been doing some work to my wife's Mustang. It is a 2003 3.8 automatic. While bolting the transmission back into the car and bolting the flex-plate to the torque converter, it made me question if the torque converter needs to be clocked in alignment with the flex-plate. Also can anyone tell me does the flex-plate bolt up just one way like many other vehicles or should I have marked it? I believe the 03 3.8 is internally balanced so I would think it wouldn't matter however the flex-plate appeared to align with the crank flange only one way. Thank you for any help in the matter

    Does not matter. Flex pate is neutral balanced.

    After installing long tube headers and a full 2.5" exhaust with cats and a new trans mount we are still getting some wicked vibration at 1500 RPMs and a small vibration at idle. Does the position of the torque converter to the flexplate matter? I wouldn't think it would.
