They do look better in my opinion but they are a bugger to fit as there is not much fibreglass left after cutting the holes.Won't be long now. I used the round lights in the lower recesses as well, they look a lot better.
Richard,
There is a damper inside the oblong vent which is operated via a lever which protrudes through the top of demister grille.
I am also fitting cable operated butterflies to the two side dash vent entries on the chassis. These are two Fomoco parts bin pieces.
There is also another cable operated iris vent on the bottom of the heater box.
Did you get your gear shift thingies ?
