I took my car apart about 2 years ago and am slowly getting it together. I marked everything but the spindles. How can you tell which one goes on which side. Does it matter, they both look about the same. And also the steering knuckles, does the curve in it face in or out. This is on a 67 GTO.

The spindles are the same for both sides. Steer arms are different for each side. They point toward the front of the car, and can only be attached one way.

Thanks for the fast reply.
