Keep the linear block on the rail with zip ties.
Remove the two Y plates and all components above it.
Remain linear blocks on the rails with zip ties or even duck tapes.
Remove the ACM back panel for the cut in the next step. Depend on the complexity of your electronics and wiring arrangement, optionally remove or keep them on the panel.
Cut/drill/sand the 2 triangles off for the Go3 rear pulley housings and then assemble the panel back.
As you can see in the picture, the 27mm and 65mm are larger than the actual dimensions so there's no need to leave more margins.
Optionally remove your wirings and electronics if need.

Install the rear pulley housings to the frame and assemble the idlers with F604zz/604zz bearings. The rear pulley housings also act as frame brackets.
3mm aluminum square spacer (8)

Don't let the linear block fall. Secure it with zip ties or even duck tapes.
Raise both Y rails each with 4 aluminum square spacers. The MGN9 rail can easily fall into the gap in an European standard 2020 extrusion.

Bolt M3 x 06 (8)
RH bolt M4 x 10 (4)
T-nut M4 (4)
Check the orientation of 20T pulleys.
All carbon fiber parts
Liquid/paste type super glue
To extend the component life and prevent fibers from spreading and make you itchy, it's best to seal the edges with super glue. No need to seal the bolt holes.
Be sure to work in a ventilated place.
(Tank CF parts are shown here but the same principle applies to Go CF parts.)
