Looking for a period correct wooden coil box with or w/o switch.
If you haven't already, you might want to also post your request on the early Ford site:
Here are the correct Splitdorf box and coils which I built for an '06 N:
Here are the correct Heinze coils for an '07 N:
The correct Heinze boxes are being built but aren't ready yet.
I build both Splitdorf and Heinze all new and totally correct. PM me if you're interested.
