upper ball joint spanner-have you?

[nu2-72]

I am finishing my front end and installing new ball joints. The Chevy book says to replace the upper ball joint adjusting sleeve and torque it to 50 lbs.ft.
Has anyone else done this?
I was talking with another member and he recalls that these are just run down until they touch and then a scale is used to test the pull of the knuckle.
I would like to set everything up as original if possible and would like to hear what you folks know.
I have also have been unable to locate the correct tool locally so am going to order one.
O'Riellys local can order but is $30.00+ and will take a few days.
Found Network Tool Warehouse online and same OTC 7080 tool is $14.95.
Called Wrench, Ball Joint Spanner on there. GM J-23447 tool and called Adjusting Sleeve Spanner by GM.
