Anyone know the size of the hex/alan key for the non-locker rear end (drain/fill plugs)? I know the C rear end is @ 14mm, is the M the same? I need to grab one after work and I have the wifes RDX here.

not sure, but it might just be 3/8 or 1/2" drive. If it is just put the rachet in there with no socket.

It's a hex bolt (6 sides) I don't think that would work. I didn't get a chance to check the size last night.
