Purpose of screw near upper ball joint '85 C20?

1 Attachment(s)

I'm considering upgrading to ball joints using upper & lower control arms from a newer C10, C20 or Suburban.
I noticed that the 108585 C20 has a a mount screw near the ball joints, C10 & some earler do not have it.
1) Can someone tell me what attaches to this screw?
Thanks

ABS wire mount on newer trucks and full sized G vans easier to have just one part# and just not use the mount if uneeded

on the 3/4 ton upper A arms the studs that the arm mounts to are larger and the ball joints have a larger tapered stud to the spindle .
Don't ask as how I know since I have 2 brand new upper control arms sitting in my garage that didn't fit my P10 :banghead:
