Hmmm . Motor City Wheels , Detroit , Mi. Manufactured these Wheels : Vega / Pinto / Bobcat / Astra / Sunbird/ Skyhawk / Starfire . The Brand Specific Center Caps and Trim Rings made these Badge Engineered be known as "Circus Wheels" . Wow.. nice castings IMHO . Do you cast these or the RWL Poly Belt Tires ? If not , may I have your source please ? Thanx
