The replacement is a "Cannondale Freehub Body for HG cassettes FH-117K K81028" which from what I've researched, is the proper replacement for my 2020 Cannondale Topstone 105.
There are slightly different markings on the old and new bodies: SCPC on the old one and SKPC on the new one. Pics for reference.

The black seal on the left should pop out with a flat blade screwdriver. Not the blue seal.
Then you can install on the new freehub.
You can take the seal off the old one and transfer it to the new.
Black seal is a general weather seal that should be transfered.
Blue seal is the seal around the actual cartridge-housed ball bearings (the new bearing and the reason you’ve bought a new free hub assembly).
