I found lots of random stuff. They work with the Army on R&D. Lots of Contracts for Hayes Wheel. They made the wheels on the Hum Vees. . . 19026 1S0R6 HAYES LEMMERZ INTL INC is a part number <a href="http://www.defenselogistics.com/search%20parts-seller%20side-summary.aspx?type=0&niin=2530015583027" rel="nofollow" target="_blank">http://www.defenselogistics.com/search%20parts-seller%20side-summary.aspx?type=0&niin=2530015583027</a> It's most likely a newly listed part number or an order for replacement Wheels. <a href="http://tardec.army.mil/default.asp." rel="nofollow" target="_blank">http://tardec.army.mil/default.asp.</a> This is the ARMY's Tank & Auto R&D site.
