Chris King have loads of information on their website about which cups you need for which kind of headtube. I know, because that’s where I went to find out which of their many, many, many different cups I needed for my Soul.
Soul uses an external cup for a 44mm headtube at the bottom: that’s the bottom cup from an InSet7 in King’s parlance.

The top cup is from a standard 1 1/8th nothreadset in King’s parlance.

You’ll find Hope are easier to get, and obviously less expensive…
the bottom is a type H and the top a type 1
