Used this same guide to replace the HDD on an A1207 iMac.
Almost identical except for the positioning of the display cable which is on the right hand side of the logic board.
Only problem was the four Torx screws holding in the display. They are so deeply recessed that I had to buy a set of Torx wrenches with long shafts as the Torx heads in the iFixit kit I have are too short.
I have removed the display from two of these MacbookPro’s now and had problems with either the left or right partially threaded T6 Torkx screws. They either come out easy or they refuse to come out at all unless you put upwards pressure on the hinge;. Otherwise the screw turns but does not release.
