Air Vents

[Learjet]

The air vents on my S1 sport are in very poor condition as are most of the Lancia's I see. Recently on Wheeler Dealers Mike Brewer found an amazing company that did spray on chrome. The results were superb. Problem is that on brief examination removing the vents from the dash looks like quite a mission. To me it looks like one of those jobs that once you get it out you cannot get it back because you have broken an irreplaceable clip. Has anyone removed (and put back) a vent surround? If so hints please.
If these vents come out easily it would be a good plan to contact this company with a whole batch of vents so as to bring the unit cost down.
