As I already replied to you by email, you don't need to create any custom jetways at KORD V2, since it already comes with 100% custom and correct jetways. If you really want to replace them, you must use the appropriate bridges, if required, or move the jetway to the bridge already contained in the terminal building.
There are plenty of bridge variations and plenty of jetways, it's impossible you won't be able to find something that fits. But again, it's not something you need to do, because the scenery already comes with the proper jetways.
Note that, at KORD jetways are a bit lower in height, since the terminal is fairly low, that's why we have a subset of jetways in GSX which works best at KORD.
