#14,is indeed a hex head screw ( screw on left). It is a #8 x 5/8.
#2 is also a #8 screw. It is 1/2" long. The one in the middle pic is what I've removed from all of the locations highlighted in the AIM.
Just wondering if AMK got it wrong or perhaps 69's used the Phillips head and '68's used hex??? Or perhaps, as suggested, the factory used whatever was on hand?
