Well, a bit more progress yesterday on insulating the drivers side bulkhead.
This is how it looked:
You can see a small grommet left of the column. There were four small holes in the bulkhead, into which I fitted these grommets (from my grommet jar)...............

You can also see how tricky this side is. The easiest way is to fit small pieces in an overlapping tile effect.

While I was under there I also added some rubber caps to the three starter connectors - to reduce the likelyhood of shorts.

There's still a bit more to do but that was all I could manage in the time available - and the fact that it was ffffffreezing.
