Answer to: Where can one obtain the iSIght kit for the MacBook Unibody 13.3"No you don't to replace the whole screen assembly. I've repaired plenty of display side related problems all under the glass. Just be carful removing the glass as it's very thin. You'll want to be carful not to damage the wiring that connects to the camera as unlike most laptops which web camera wiring run under the display, this MacBook wiring runs in a grove right under the glass on the right side(if you are looking at the display). Good luck.
