MNSmith,
Sorry to digress as I know you wanted to stay on track with your plan. In answer to your question as to whether my '57, 3600 hub is same as single wheel, the truth is, I don't know. From what I gather in these postings it is not. As to whether it is same as one ton, don't know that either. Perhaps someone reading this knows for sure if it is. I can take photos and post or email them if needed.
