You have to purchase new fog lights from ARB. They are cheap...about $75 for the pair. The OEM do NOT fit.
You have to cut the original bumper and a section of it goes back on...then you put the ARB bumper on. If you call ARB USA they will forward you a copy of the manual for installation.
After asking you, I found a detailed link provided by you during the installation. It looks awsome except for the small gap. Were you able to close the gap with some type of gasket? I will contact ARB for the procedure. Thank you for the response. I am a new member and still try to navigate around this forum.
