You will also have to print the bearing holders for the Y axis from the 2020 files. print more endstop holders. 3 motor mounts 2 Z 1 Y. If you but the beam set, there is a tonne of parts needed. I did a guys Acrylic to 2020. I cut all the 2020 myself and bought the nessessary parts to do the upgrade. IIRC it was $118USD to Canada. the whole kit is 119 plus shipping.
Its better just to buy the upgrade kit and they few parts to go with it. By the time u add the screws and the cable chain and few other odds and ends like the hidden corners and the screws and nuts etc etc Its cheaper to buy the kit. I only did it because we are both into R/C and have stuff for them, its mostly all 3-5mm screws.
Just my 2 cents.
