I have a brand new canceling type hub with horn copper ring for Mopar that came with my new wheel that I didn't use because the one on it from the grant it had worked just fine and is in good condition.
Let me know if you think it can help you, and in the meantime I'll see if I can find the install kit number it came from.
I know for a fact it was a Grant kit for Mopar.
Found it.
The box says C03-5P and came from Forever Sharp wheels with my billet wheel.
I'll see if I can find it on the net and post back.
From what I can see on the kit you have it doesn't have the cancelation stud for the signals.
This brand new billet adapter I have does, and it fits the three hole spacer/adapter for the 5 hole wheel and my center cap looks just like yours does.
