Grigg - What mounting system do you think that is? Maybe an "AR" three piece. The kind with a solid side ring and real small split locking ring? With the paint it's hard to see whether the small ring is there. Motor Wheel would have used the same variety of outer rim designs as would Budd, K-H, or Firestone. I just can't think of anything that it would be other than an "AR". Stu
