is it possible to move the entire power window regulator system back (toward the door skin) about 3/4" for added clearance for speakers with a deeper mounting depth. Putting in audiophile grade 6 3/4" midbass drivers (2 each door). One closest to the front of the door is no problem but putting one next to it would fit if the windows were left down all the time but will hit the big gear when rolling the window up. It looks like moving the big gear part back would not affect the actual glass track.
