DT Swiss RR 21 replacement freehub body

I need to replace the freehub body on my RR 21 wheel. Is there anywhere I can find out which type it is without dismantling everything?

    If there is a technical drawing or manual online, otherwise you need to dismantle... in fairness the latter is probably quicker

    Traditionally, the RR21 use the DT240 hub, hence the ratchet system

    DT240s on mine - printed on the hub. Disc version from about 4-5 years ago.

    Managed to dismantled it, but there's no model number printed. Looks similar to HWYABX00S2775S seen online which claims to be compatible with 240, although mine has 240s printed on the hub.
