My advise would be to send a message to sgparry0407, he has obviously figured this out (although I just now noticed there that the output pins in the 4070 are offset from the grid by a fraction in schematic when they are in the original place but snap in correctly when moved out) and the pins seem to connect correctly and he seemed happy to share. I think the forum should be copying him as I mention his id, but since it isn't highlighted I think I'm not doing something it wants to identify another user.
