On page 276 of Trident R2 assembly manual (commit hash f04f747 ), the keystone inserts shown is still the R1 version.
I found this because I tried to hack a keystone insert for a SMA Wi-Fi antenna and found R2 blank keystone more easy to hack, so I printed the R2 skirt part (not sure whether it changed between R1 and R2) and two R2 keystones, then I realized that I don't know how to insert R2 keystones.
