Happy Holidays!
Hi, I recently bought a couple of Elitewheels Ent + adapters, as soon as I get my hands on them I can provide pictures and measurements, if that's of any help.
Where did you get the adapters? I am looking for them and can't find them anywhere.
I had the RD07 (pawl) and RD13 (ratchet) hubs and can confirm any generic free hub is compatible. Based on this, I believe any QR end cap would be fine. The products on the mana store are expensive.
