I don't know..the 9 inch spindles had the mounting bolts loaded in shear, according to a tech editor of a Mopar magzine,and the idea of "lopping a ear" off and putting more stress on the spindle has me "skairt" as we down here would say.That said,if the maker of this "kit" had a simiar set up that used 10 in. drum brake spindles without cutting up the spindle,I'd be tempted to try it,GM bolt pattern and all. On a unrelated subject,if any one in Colorado is listening and wants a 62 big block car,theres one in parts cars on e-bay under Plymouth that sounds very solid..Someone get this before some wonderboy puts a BUICK 401 nailhead in it. happy with drums in Mississippi Randy Routt ---- Please address private mail -- mail of interest to only one person -- directly to that person.
