The measurements for the LHS spacer are: the narrow part towards the outside of the spacer is 9.7mm. I got readings of 9.6 to 9.8 mm, so 9.7mm is good. Now, the raised section that faces the wheel bearing is 10.7mm. So that wider section is 1mm wider. ID is 15mm and OD is 34mm. The RHS spacer is 7mm wide with same ID & OD. Cheers.
