What is the correct orientation for the front strut mounting bearing? It is located under the strut mounting insulator. Does the open face of the bearing face up or down?

On the rear suspension there is a spacer that goes under the strut mounting insulator. This spacer is missing on both of my 240Zs. I am debating if the spacer was lost over the years or is ok to to just leave it out.

Thanks

Here are some pictures of how the strut assembly goes together. It shows that the strut mount bearing goes face down.
