I want to thank everyone here for all the fantastic advice and the links to part sources, information, and so on.
I will certainly keep you posted as to the progress.
Fortunately, I've also got the help of a retired uncle who was a mechanic "back in the day" and worked on these engines daily at one time. He's a great resource and is also enjoying "coaching" me through this repair since his health no longer allows him to turn a wrench.
