Strut rod washers.... correct way to use.

I have seen earlier cars with concave side to bushing and i think somewhere around 73 it changed.

Are you sure that someone didn't change them and put them in wrong? I've always seen them with the curveature away from the rubber on both sides of the bushings.

We just removed the lower control arms from my son's 71 virgin Valiant today and the curveature was away from the rubber bushings.
