Turns out the bolts is the problem. The Shoulder was to short to allow the plate to sit far enough from the wheel for the cap to make contact.
I had to notch the plate myself, and leave the 3 bolts somewhat loose. I think I will put some locktight on the.
BTW, I emailed Grant, on Sept. 27. They replied saying the plate might be wrong and they were sending me another one.
I have never recieved anything from them.
