How to replace Stegbar Sliding Glass door roller wheels. Part 2

See Part 1.
I have a Stegbar Sliding Glass Door. It's trick to replace the roller wheel cartridge because is actually need to shift the right and left aluminium frame so that the Adjustment Screw on the Roller cartridge clears the tiny "aluminium lip" at the bottom corners of the right and left frame. When you have clearance, tap the bottom frame off/out so you have access to push out the old Roller cartridge. The frame with to door lock is the hardest to budge. But I managed to shift it 6 mm so that it just clears the screw head. Please read my instructions in Part 1 for detailed instructions.

What screw size did you use to put the door back together
