Hello,
Not into automotive technology, frankly, but just curious.
a. Do most GM cars these days use Metric screws & Fasteners (other than for the engines) ?
b. How about for the engines ?
c. Foreign cars ?
Thanks, Bob
Metric has been part of automobile manufacture in the US for at least 25 years. Many GM cars are built and or designed overseas so it is just natural to use metric. There was a recent thread about GM cars that are Opel and Holden sold under other GM names. Going metric just makes life simpler. Don't for get that some cars like the Toyota Vibe and Mitsubishi Eagle are joint ventures coming down the same assembly line.
As for foreign cars if you live in Europe the US cars are foreign. Yes, they are metric.
Keep them Whitworth wrenches though, they may become popular again.
