G37 shift knob size/ shifters that will fit

[$tevenG37]

hey guys i was just wondering what size the G37 shift knob was. i wanna either purchase a momo shifter or a nismo. i had a couple of questions like if the nismo shifters will fit the g37 if you buy the one made for G35...? and if a momo shifter will fit the g37 such as the gtr2 shifter or nero. the guy at momo said it will fit the g37 if its 8 to 15 mm in size. well if anyone can help me out that would be great thanks guys!
