Hello there, william.m.baker!
Thanks for reaching out to the Apple Support Communities! Sounds like you are trying to get Widgets installed back to your Mac. I know I love to be able to access all my Widgets and install ones that I need as well. Check out this article here with steps about Mac Basics: Dashboard gives you quick access to frequently used info.
To see all the widgets on your Mac, click the add (+) button in the lower-left corner of the screen. This enters the widget browser. It shows you all the widgets installed on your Mac.

To add a widget to Dashboard, click an icon in the widget browser. Or start typing the name of the widget in the search field and click the widget to add it to your Dashboard. You can even add more than one copy of the same widget. This can be useful if you need to track time in multiple time zones, or want to create multiple Stickies.
Download and install more widgets by clicking the More Widgets button. This takes you to the Apple Dashboard downloads webpage.

Cheers!
