Thanks guys - I have more from this evening to share!
Remember that little bolt I mentioned in my last post, the one that connects the centre vent flap lever to the actuating rod that I said I would take a picture of if I could get he camera up in there? Well it did it!
Now it was time to line & pad out the floors... the carpets have a 1/2" thick layer of foam on the underside that moulds over the rear floor vents and such, but the crappy water absorbing 1/2" thick foam matting stick to the floor has been removed so the carpets were sagging a bit - but I found a solution!
First I treated the steel floor to some rust converter and a lashing of Killrust paint - then I took some thin rubber matting I got from Bunnings and trimmed it to line the floor
I also got some Welcome mats from Bunnings too and chopped them up to fit around the floor vents
Then it was just a matter of layering the floor pieces down...
And she is done - for now.
