So my quadra arrived today - great piece of kit and it is the newer RX version....
So how easiest to mate it with anything with an 8mm shaft ....
Easy
Get one of these (I already had them for SB-900) and use a spigot in the quadra and screw to the bracket ...

no messing and keeps if as close as possible to the centre axis
