The 62mm pulley came with a "spacer" that appears to mount to the front of the pulley but perhaps could go onto the SC first then the pulley that way no shims needed. I tried to include a pic of it hear but not able to do do that from my phone. Will post pic when I find that charging cord. By the way the spacer seems to be too thick to use as a spacer. Least 1/8 inch
