Thanks for the great idea, Janey.
Fortunately, I was able to compare my work to a completed 66-1 and found the holes.
Now I have a tiny zip lock bag trick. When I take out the screws, I slide it into a baggie with the appropriate parts. Things are going much smoother now.
Thanks for all the input. This is such a great group!
Wait? Your going to leave us all in suspense? Where did they go? 😁
