RCM Mike has the
Dace adapters too. The Dace uses 22mm or 7/8" sockets whereas the Proline's need a 23mm wrench which you may need to buy from Proline as well. I have the Dace adapters, and they are pretty nice. I bought Dace because of advice from other RCM forum members. No regrets!
EDIT: the Dace adapters are available in black or blue.
