Pannasonic Q Drive tray problem

[+eebuckeye]

I received a Panasonic Q that the drive will not come out.  The belt seems ok and the gears move, however, the tray gets stuck unless force is applied at a specific point.  It appears to me the tray bottom has pieces broken off around the corner which appears to be where the drive is getting stuck when ejecting or closing.  Anyone have any suggestions on how to fix?  Is there a drive tray I could use to replace this one?  The belt seems fine and moves the drive when it is past this spot.

 

Thanks!
