Standard what?

Starting working on a plan of sorts for the build sequence.  Most steps involve wrenching on the car.  No problem, I’ve done a lot of work on cars over the years, and have a good assortment of ratchets, extensions, and wrenches, from 6mm all the way up to some 30+mm axle nut sockets.

Wait, mm?  This is an American car built in the ’60s.  Before we’d been to the moon.   Before we were using metric fasteners on our cars.  Stopped by Sears while out today for some good-old fraction-based sockets and wrenches.
