Use this as a learning experience as to what the "control arm" is. At one time, we all did not know this term, and what this item was.

Are we talking about this part I have outlined in blue is the control arm, and I'm going to hook onto the lip of it where I marked in red, if I get one of those square-body jacks that has the hook?

I see the LMC catalog labels the part Lower A-arm, so I suppose there are 2 names for it. I am understanding the higher U-shaped part of the jack cradles the rear axle. My hydraulic bottle jack has no such U-shaped part, so that is what makes jacking so hazardous if I have to jack at the axle and have not fabricated some sort of device to go between the jack and axle. I would rather just get the right thing. 1974+ Chevy truck jack with the hook and long folding handle, I'll have a look around for that.
