This may be more of a car question, but I couldn't find an auto repair
group to ask. I need to pickup a last minute Christmas present for my
dad. I was going to buy him a dog-bone socket wrench. I'm not sure if
I should get the SAE or metric. I really don't understand the
difference between the two. Any suggestions? If it helps, we live in
the U.S. and most of the cars he works on were made between 1988 and
2004 with one being made in the 70s. The brands of the cars/trucks are
mostly Chevrolets and Fords.

Why not ask service managers at the nearest Chev or Ford dealers?
