The Motor wheel Spyders were used by alot of Stock class racers and some used on Early ProStocks. I heard Motor Wheel gave the wheels to racers? The other wheels are Motor Wheel Fleas. Rear wheels were called Fly's, front/Fleas. They were the lightest wheel you could get back in the day. VERY hard to come by now days, and when you do they are expensive. Those Mag Spyders are probably more rare then Fly's... You also saw more Spyders on cars like Oldsmobiles. Not too often on Mopars.
