I just put a new set of Alcoa wheels and tires from a 2004 Airstream on my 1976 Sovereign. The old lug bolts not only don,t look very good on the new rims, they seem to countersink to deep in the aluminum rim. I need new chrome lug bolts with a longer bolt head. I called both Airstream parts and Inland RV, neither were much help. Does anyone know the size, part no.,or any information that would help. I also visited a store that sells nothing but new wheels and they couldn't help.
