Thanks for the support. The why will probably never be answered but the "correctness" is being established for Janesville as a normative build. The serial numbers, as the trickle in, will help fill out the known pool and hopefully help people who have wondered if their truck is correct or why everyone else's is different. It is too easy to dismiss an apparently incorrect truck as a hack job repair when in fact there were variations from the various plants.
