Those CV4's do look pretty close. I found these searching for CV4 Replicas. Looks pretty close with a similar finish and slightly raised center cap, but know nothing about them.
I believe I found the original picture from Mike Miller Subaru in Utah website. I'll try to reach out to them.
Fingers crossed that someone in Utah that is the lucky owner of this fine setup is possibly a member and stumbles across this thread and can provide the details on his or her wheels.
