I really don't think that all the yellow bolts should, or even can be loosened. Only the M3X8 BT, or in extreme cases the three per side middle bolts holding the 2020 in place.
I found it to be easier to install one bolt not fully tight on the left, and then carefully slide the cartridge with attached x-axis assembly and the right hand carriage all the way to the front. Then loosely install one bolt on the right to align everything. I alternated loosely installing one bolt, left then right, until all eight were in.
You want the M3x6 BT packet

These are the M3x8 BT with the blue thread lock pre-applied.
Be sure to check the little triangle is resting on the rail.
Do not use the M3x8 with the blue thread lock here. They are used later on. That bag has a "B T" at the end of the description.

The M5x8 are from the prep of step 6.
