So, scored some fog light surrounds off Doug, they were blue, I had a black spray can on the shelf.
They are now black.
Threw a few of my big bucks around and bought two funnels from bunnings for the pricely sum of circa $5. Ends are perfect to slide the 2 inch ducting around.
Trimmed them up a bit.
Drilled a few holes, tidied them up a bit and pop riveted those mofos in.
I love pop rivets.
Cut the ends off the funnels and in they go.
Just have to feed the flexy ducting through to the ducts on the hubs and all sorted.
