The brake lines on my '97 Jeep have metric fittings on one end and

g There have been some messes out there. Chrysler supposedly was
all-metric by the late '70s, and my '89 Caravan was, but I didn't try
to turn every nut and bolt.

Here are GM's metric standards for suppliers as of 1999. They include
soft metrics:

There probably are a few bits of inch/Imperial stuff out there. It may
be that a few suppliers are still covered by the soft-metric
standards.

Maybe those imperial fasteners were left over AMC parts!
