Because it requires more modifications than just the opening and I don't want to spend time looking on the internet for a wrench that will take me additional hours that I can't really spare, and for which I do not have the proper cutting and grinding tools, and if I did, I will use it exactly one time and never use again because I'm probably going to get rid of the car in a year, and because someone on this forum likely has said modified wrench lying in their trunk, or at the bottom of their toolbox, and because I promise to give said wrench to the next person on this forum who asks for it and because I'm lazy. (respectfully submitted)
