Like Victor, I bought the genuine GM mudflaps for about the same price. Quick to fit and the correct fixings supplied. I bought them because a stone broke the front window of my caravan: surprisingly, the Caravan Club insurance did not cover broken windows so I paid over £500 for a DIY replacement and changed my insurer. Also, when I ran over a discarded exhaust on the motorway my front tyre was destroyed but the mudflap saved the wheel arch/bodywork from damage. A worthwhile investment.
