I seem to have run into a brick wall on the lug bolt question for installing Aluminum wheels on my 1976 Airstream. I have not been able to find either a chrome lug bolt replacement or a screw-in wheel stud to replace the lug bolt that anyone feels would do the job safely. No help from Airstream at all or Alcoa or any of the other wheel distributors. One suggestion was to replace the wheel hubs but that is a big undertaking that I really did not want to do.
I was encouraged when I found this post on the forum from user name "Tim and Cindy" posted on 5-16-04:

However the advise I received from Airstream Tech was not to use studs and I have not been able to find the screw in studs from Summit racing mentioned above. I was hoping to get more details and part number and sent a private message to "Tim and Cindy" but no reply and this was the last post by him on the forum.
Still searching for a way to do this, any help or suggestions are appreciated.
