Was down at the local holden dealer this morning to inquire about having a tech change the blue scalps on the mirrors to the black ones, no probs he said, it will cost 80 bucks to do it he said..........Thanks I said but No. The parts guy was more helpful, he asked a tech how it was done and as a result I was provided with a document to depict the process. Went home and did it in 2 minutes total. Very easy. When looking at this image and you look at part #1, it is here that you depress the plastic to release that single clip and whilst depressed lift the scalp up, there will be a big crack and the part comes off without damage. Install is a reverse of this.
