I had the opportunity to buy at at half price a set of factory sun visors for my 2008 4/4, and have found these useful when the sun is low on the horizon.
However, I find that they do not readily stay in the'up' position but tend to flop down which is annoying.
Can anyone suggest how I might rectify this.
