22mm hole in the yoke.
The two M4 screws are 31mm P.C.D from the centre of the 22mm hole.
The OD is 40mm.
I vaguely remember testing them in 2008 0r 09 before CRG made them standard and I don’t think there was a problem fitting them, except the M4 mounting holes where 90 degree off, i.e side to side rather than front and back.
Remember you’ll need a longer kingpin bolt too.
