G650X thickness of the washer under lower race ?

[bighair]

Hi
Anyone know the thickness of the washer/shim under the lower steering head race bearing ? mine is on an X country but any X they all have one.

No 10 in the parts diagram

Put new bearings in mine and must have damage/lost the one used for the old bearing when removing and relpaced them without and it just catches the frame on full lock.
So I am going to drop the assy of again and put one in.

Thanks
