Drag Link Ball Joints

[Old Radio Tech]

65 K10 Suburban with:

GM 7802644 Power steering box (not Original)
Pitman Arm has MO22 on top and D8TA-3590-BA on the bottom
No visible numbers on drag link, 13" Ball stud center to ball stud center
Steering arm has 4A3R86 and F31504 on it

Ball joints use a 15/16 wrench, stud threaded for 5/8 -18, bottom end opening approx 1 3/16", and overall length about 3".

Looking to positively identify pitman, drag, and get good PN's for the ball joints.

Thanks,

Paul
