Hi Guys, Not sure if anyone may be interested, but I have just installed a custom antenna boot mount on my car. The issue I had was now driving an XR6, the standard L or Z bracket wont clear the spoiler when you open the boot. After lots of hunting on the internet, I found the company that makes the mounts for the NSW Police cars. Company is Industrial Evolution in Sydney. www.industrialevolution.com.au After a little bit of trial fitting and tweaking the angles, very happy with the install. Cost is around $33.00 including express post.
