Chosen Solution
I picked up a used 2.26GHz A1342 (Late 2009, MC207LL/A), and the instructions in the user guide take special care in noting that the bottom panel has two different types of screws at the front and back (https://manuals.info.apple.com/MANUALS/1...). However the technician’s guide for this model just refers to them as “8 (4.3-mm) 922-9208 screws”, and mine came with regular screws without the shank/shoulder in all 8 positions.. Could someone who got one of these new tell me if they got two different types of screws?
I could not find a model on that guide. I also do not remember ever seeing this set up on the screws. Anyway here are the screws listed for this model: MacBook Unibody (A1342) Lower Case Screws I suggest you take a few out and see for yourself.
