Mine is smooth finish as I folded it out of 1mm steel, I also used the cigarette lighter from the Escort console[along with all the switch gear] as it was backlit. Ford panel did not use this as it fouled on the duct work.
Ford did raid the parts bin in creating this option and I wandered wrecking yards looking at different vents I could use and few were suitable [one that was on the short list even had a small motor that oscillated the vents]. however I stuck to Cortina vents just to make it some what look more original. Then I had the decals made up just to the dress it.
Interior was the easier bit for me, I had more dramas fitting the compressor in the engine bay as I did not want to relocate battery as to keep the car factory original, my compressor mounts under the alternator as the after market units did, however I wanted to fit extractors and these fouled on the alternator, so every thing needed to go lower, so low that the compressor belt goes through the bottom radiator hose.
All the mods that I fitted to this car are reversible easily as they are only bolt on mods, that's why the battery had to stay were it was. My RS was a one owner car and I did not want to butcher it. That's why I took this course.
