Its in place, and I found the heater duct, number 14 on Diagram, Will I need number 11 ? as don't think its there , also number 12 is a foam seal, Im sure I could make one out of some thick foam, or should I get the correct part ?

I wouldn’t advise making the heater to bulkhead seal, as it’s a difficult shape to get right, and the one I made is useless. The one in the diagram for #12, I also made. It seems to be doing its job good enough.
