The 3/4 drive brings to mind an interesting story......
A number of years ago, I broke a front spring on a Freightliner tractor I had. The cap nuts on the u-bolts were 1-1/2". I torched off the old U bolts, replaced the spring and installed new cap bolts ant U bolts. Anyway, I didn't have a large enough impact to produce the 500 lb/ft torque that the nuts required so I took a Sears 3/4 drive 1-1/2" socket, breaker bar and a long pipe and applied it to the cap nuts. Because the nuts are under the truck in the front, I had my wife hold the socket and bar up so it wouldn't fall off. As I tightened it up, the socket broke and a peice of it went zinging past my wife's head at the speed of light. It grazed her forehead, right above the hairline. Bleeding profusely and calling me everything under the sun she went into the house. After she calmed down, I asked her if I got a new socket, if she'd hold it so I could make sure it was tight. You know what her answer was. I think I had pop tarts for dinner that night!!
By the way, I took the socket to my local Sears and Grabbuck and they exchanged it!!
