Has anyone put a full size spare tire in their taurus, SHO or not? The Performance Pack has the mobility pack but that wont help in some situations and I would like to buy 5 aftermarket rims so that I have one to use as a spare in the trunk, but I dont have access to many tools where I am at so if it wont fit from the factory I am SOL. Thanks for any help or advice (if it wont fit, I will look into getting a factory ford donut and jack)
