Can someone do me a quick solid and measure the OD (outside diameter) of the shaft (ha) thats circled very poorly in the attached image? 
I may have forgotten to do so before I drove 6 hours away from my kesev.

preferably from a k50 box, dunno if k40/50/t50 are all the same

Thanks

Hi Ethan,

             My vernier says 13.8 mm at that point you have circled.  The shaft actually tapers slightly (gets thicker) as it goes towards the swivel ball thing.  So generally, that area of the shaft is between 13 - 14mm in dia.

Trust this assists.
