5'' from outside edge to rim centerline.

5.875'' from mounting flange to outside edge.

Which then equates to .875'' (22.2 mm) positive offset.

Margin of error + -.125''

Can anybody else confirm or deny this?
From true center to mounting pad is .875?! If so you are dead on. I was thinking they were 20mm OEM.
