Welcome our new members from Alaska!
Glad you came on board and are ready to put some personal elbow grease into a real classic.
If you haven't already noticed, there is a ton of information and help here. Tom, one of the site moderators is a wealth of information as with many others around here.
I too have worked on a couple of older Newell's including another go around with a '78. Recently started re-upholstering the booth, which is almost done. I will start a new thread under the "Interior Works" section of my project and will include some photo's of the before, during and after.
Don't forget to take plenty of pictures of your project.
Ken W.
