Vintage 15x6 International Dragmaster Wheels, 5 on 4.75"
 

These are super hard to find in the 15x6 size. They are one of the few wheels that clear '67-68 Z/28 4-piston calipers without spacers. Price is pretty fair IMO.

That's a nice looking wheel

I agree - they are killer! They have been relisted for less $ in the link below.
