I believe those wheels are 2 halves, welded together around the center, with a stiffener between the halves in the lug face section of the wheel.
Your set happens to have the spindle mount hub in place of the stiffener.
The wheels only come apart by cutting the weld around the center......cost to remove the spindle mount hub and either replace with the stiffener or machine the center out of the spindle hub and re-use it, then weld the two wheel halves back together will be pretty prohibitive to this entire job.
You'll likely have a hard time even finding anyone to do it. Liability reasons.
