OSH heim joints for homebrew swaybar disconnects

i dont have money for the jks disconnects so i am trying to make some homebrew ones. anyone have any opinions about the OSH parts i have used? i drilled and tapped in some zerks to make them greasable, grease will reach the ball, but would want to know if anyone has experience with the Orchard Supply Heims. I thought maybe they will be ok for oem sway bar use. You think they'll stand up to the pressures of the sway bar? sure would make it easy to make my own discos with them. here you can see one fully extended with 1/4" thread in the heim and the other is collapsed. heim is 3/8" hole in the spherical ball.

opinions welcome, criticism accepted!
