Dave,
I have enjoyed reading your truck story...interesting read if nothing else. You most certainly have the determination to make this happen and that is a huge plus. From my experience; will, determination, and dogged perseverance are a must when working with old obsolete iron. The one problem I see with your situation is that if you "cuss" poorly implemented previous mechanical repairs on your project, you may make a relative mad at you...tread carefully!
Your compression readings are all real low, so low that I would question the accuracy of the guage. Did you check compression with all of the spark plugs removed using a freshly charged (good) battery?
Also, have you gotten a parts manual for your truck? Finding parts by part number is a great way to locate parts that no longer show up on modern computer systems. Google is your friend.
Keep up the effort!
Paul
