Hell Calsdart, Unless you are building a 100 point clone I would not worry about it too much. However, Greg is in North Carolina researching what is probably the "most original" 2 owner non molested surviving 1968 LO23. Once he returns with all of his research and pictures I will be happy to share with you information pertinent to the a arms :). I just used the K member and control arms which came on my car and restored them.
