What is the specification of the extra screws needed to install a second drive to an upper-drive populated Mac Mini 2012? I ordered the wrong OWC Data Doubler kit. I didn't notice the note saying that some Mac Minis have an upper drive configuration and that it would require a variant of the kit with additional components. The additional items in the variant are the 5mm wrench and 2 set screws. I considered exchanging the item but the local shop that imported the item is charging me for the return. Does anybody know the specification of the additional screws that I need? There's a similar question I found here Can the 2011 Mac-Mini (not the Server Edition) Support an Additional Hardisk, SSD?. But it's unclear whether the ifixit kit mentioned here is for the lower drive config or upper drive config Mac Mini.
According to iFixit's HD replacement guide for Mac Mini 2012, you need both a T6 Torx screwdriver and a T8 Torx screwdriver. The guide shows the corresponding screw specifications for each relevant step (IE two 6.6 mm T8 Torx screws), but iFixit only sells the screwdrivers, not the screws themselves AFAIK. They do, however, supply you with the information needed regarding all the relevant screws.
