correction shims are 7 degrees.

just got off the phone with ron boggs with sierra bronco. said the early bronco shims (67-77) he's using is 1" from center to center of the bolt holes. he said though, the upper shims are designed to fit inside the upper retaining ring, no matter the spacing or model of the bolt holes. i told him i'll be receiving my new lower coil cups in the mail in a few days. when i do, i'll measure the distance on my new cups and he'll take that distance and make me a new pair. little more than $70 though because of the labor on the side.
