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

I read someplace that the concave washers are also used on other Hi Volume sale part numbers, that are more important than our Mopars, for those the cup goes away from the bushing. The correct way is for the washer to cup the bushing. The service and parts manuals both show the washers cupping the bushings. Thats ok, I've done it wrong all of these years too.
