chevy d44 ball joint question???

[nshefbuch]

i'm installing new (everything) and on the upper ball joint, the threaded sleeve that goes into the "C" of the axle, how far do i thread this? flush on top or bottom? ball joints say they are a "zero degree" camber - from napa

also, when you get front end alignment do the shops adjust this sleeve?

thanks for any help
