Belt drive C20XE

Belt drive C20XE + KAT Question Aloha! Got in the garage nen C20XE, z Zt. still without LiMa and therefore also without belts. LiMa would have to come now the days by mail, only the question of the belt remains, because I still have to get it. Were there different variants? My knowledge there are nn V-belt and a V-belt, which do I need? Do I see this on the belt disc? Sorry, have still net so with engines, but am really learningable Does anyone possibly have accurate photos of the belt drive? And an indication of which belts I need?! Servo pump does not have to be driven with, because I have an electric servo. So actually only the LiMa that needs some movement, but hope you can bring me some enlightenment thx -fate- edit times still another general question: if I need a cat from a different car, which has a bore for a Lambda probe, which I need but net, then I can just do it with a screw, but I would like to do it again.
