Wow! Mark sent me this thread. I CALLED these folks (couldn't believe they didn't have an email address) to see if we can use their chart. Left a message. They had some other cool thing on their site. Not sure if it's helpful for truck restoration. But looked like neat engineer-speak stuff.
Hopefully, they'll let us use the charts. If they won't ... well ... maybe our Tech Tip will be just "go Google!"
Stay tuned.
