Your link is to the Lifeline QR, as fitted to the pre April 2017 M3W. Marmota has a new M3W with a Traven QR. The splines on the steering column for a Traven QR are not compatible with the Lifeline item, they are not interchangeable. You can buy the Lifeline item via ebay and several other outlets. I suspect that the Traven QR, like many bespoke M3W items, is only available through Morgan, if they chose to supply it, which it seems they will not at the moment. Excellent customer service.
