Tony, The UK version of the Spark was not sold with wheel trims on steel wheels, as I previously pointed out. A look at the steel wheels shows that they were never designed to have wheel trims, but just centre caps, as they were supplied with. You can clearly see that the wheel centre offers no normal means of attaching a trim as the centre is near flush with the outer rim.
The OP didn't bother to be specific or indeed take the time or trouble to take and post pictures of his wheels so that we could offer precise assistance. Missing your wheel trims or centre caps is not really a show stopper either.
Currently, I am looking for the small cable that connects the radio steering wheel controls to the clockspring on a 2011 Aveo LT. This is because I have recently fitted a very nice leather steering wheel from an LT to my Aveo S, ( the original plastic wheel was polished shiny and the texture removed due to the 600 miles a week it does) but it did not come with that tiny cable. So I still have to reach over to press the buttons.
Please tell me where I can order one from. I also want it cheap and quick.
Not that simple is it?
