Whats up everyone...I just got an H13 HID Kit for my 07' GT500, When I attempted to install them, the instructions were wanting me to drill out the back of my lamp housing. Which I am not too thrilled on doing. I have been looking around at different Kits and reading some of the instructions which are telling me to do the same thing. Is this normal for getting HIDs in a mustang? Does anyone know of any other HID kits that will not require this? Also to be virtually "plug and play"?
