Cannot extend admin-tools blocks into new templates

Hi friends!

I'd like to be able to extend the admin-tools blocks into my new admin templates, but can only extend:

{% extends "admin/index.html" %}
{% extends "admin/base.html" %}
{% extends "admin/base_site.html" %}

None of which have the admin-tools blocks with the appropriate css and jquery. Is there a specific template I should be calling on instead?

Thanks,
