So metric bolts are nothing new, I have had my metric tools for years and they were not purchased for the Crossfire or any foreign made vehicles. I also have a couple of sets of BSF/BSW wrenches as well, these are about fifty-five years old.
Yeah, no doubt Metric & SAE fasteners have been in use on Detroit iron for some years. An example is my 2006 F-150 STX 4x4 Flareside. It has a 4.6 liter V-8 under the hood. And depending on where the motor was sourced from (Ford had 2 motor plants for this engine), the oil filter connection is either a 22 mm thread or a 3/4 inch thread. Mine has the 22 mm thread.
