Here are some updates. I have been playing this for about a week and have been working out some bugs. On the alignment, it seemed to affect the caps on the tuner when setting the alignment with the shield off the tubes. When I reinstalled the shield, I had to adjust quite a bit the front and middle trimmers, the back #4 wasnt affected much. It didnt change the IF alignment. As I finish this project, here are some notes.
Here is a pic of my RF coil rewind:
