How to replace trackpad on late 2013 15" MacBook Pro

Hi There,

Although people point to the 13” instructions for replacing the trackpad, the actual trackpad is a very different part which also attaches differently.

Questions…

1. If you don’t know the exact screw sizes, it’s very easy to strip the heads so I don’t want to guess. Does anyone know the sizes for the 6 screws per side which attach the trackpad to the case? See screws highlighted in yellow .
2. The screw circled in red is not seated properly and is kind of jammed on an angle which is why the trackpad isn’t working. Others say this is a Torx6 screw but it just doesn’t seem right. Now that it’s jammed on a slight angle, what’s a good way of getting it out?

Any help would be much appreciated.

Cheers

Ben
