Jimmy carter was the jackass who stopped us from switching to the metric systems decades ago. Amongst his other disasters. Passed by congress, moving forward and then last minute personally blocked by Carter. He is 100% personally responsible for us being decades behind while he catered to the auto industry. Not being up on your history is narrow minded.

I believe all domestics are metric now. Not sure when GM started with metric motors but the bodies have been metric forever. I wish everything was metric. The only thing I dont like about metric fasteners is they have 3 or4 differnt common thread pitchs.

well thanks for the history lesson,now we can all be like you and hate jimmy carter.

t ain't the wrench size, it is the threads u gotta worry about. u can get away with metric wrenches on sae bolt heads-usually and visa versa, but don't go mixing up what bolt goes in what hole...
