Negative camber

Just to be sure we are all talking about the same thing.

The tops of your tires are tilting outward.

This can only happen if:

  1. The upper control arm is too long ( b, c, e, body????)
  2. The upper mounts / frame rail are bent outward
  3. The lower control arm is too short
  4. The pivot pins are excessively worn
  5. The bushing is missing
  6. The k member is bent inword or wrong

Backwards. Negative camber is when the top of the tire is tipped in toward the frame, not out.

B/C/E body UCA's will not physically mount on an A-body, the mounting ears are a different width.

To the OP, pictures of the issue would be very helpful.
