Canon 5D (Mark I) Mirror Replacement Part 1: Disassembly

Disassembling a Canon 5D with missing mirror. I could not find the mirror itself for sale, so I had to buy a new mirror box assembly, hence this requires the full disassembly of the 5D.
This video is the first one made using a NEX-5T instead of a Fire Phone, so far I'm finding the sharpness is not that great (using an old manual focus 28mm f/2.8 lens set to f/8) and the field of view is smaller.
I am using the 5D parts catalog found here for reference: drive.google.c...
I am using the Moody Tools JIS driver kit found here for disassembling the camera: www.amazon.com...
And storing screws in a Yongcun 24-compartment bead organizer found here: www.amazon.com...
I write in the various screw sizes in the compartments (M1.7x2,3,4,etc.) and check screw sizes against a to-scale printout that I drew in Fusion 360.
