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

Just a thought about this...I remember my '69 Charger had the washers concave toward the bushing but the replacement bushings had the washers marked to be installed opposite this. The original washers were fairly flat with a slight curvature. The replacement washers had the more pronounced angle like as seen in 70aarcuda's pic. Maybe the difference is the replacement washer would compress the outside of the bushing too much?
