How can this be easy, but the Blu-Ray drive be considered Moderate? You need to complete the Blu-Ray drive removal prior to replacing the laser lens, which means this is at best a Moderate task.
I used a #0 without any issues and 0 stripped. I used the #0 for all screws internally and externally. The head was sharp and I applied adequate amounts of pressure when loosening the screw.
I finally received my SD Card Reader (which was mis-routed twice by USPS). I the SD Card sits on top of the head guard fine, but without the adhesive it will come up slightly. This was minimized when putting the 2 screws back in.
The assembly was simple and unlike many others, I had 0 stripped screws.
I am happy to report that after putting it all back together the issue was resolved by the $7 replacement part.
At this point it's a lot harder to get the SD card split from the heat shield under it. The epoxy is pretty adhesive. Because of this I bent the heat shield and it broke from the solder joints on the internal side of the SD reader. I'm hoping a quick retouch of the solder will adhere the shield back above the processor without any additional damage. However, that won't be until tomorrow when I check / test it. I'm also awaiting the part to arrive which should be within the week.
