Simple UIScrollbar question

Noob with a quick question: Is there a way for me to change the width of an instance of a UIScrollBar component without reskinning the whole thing?

I’m looking for a quick AS fix to just make my scrollbars narrower. Resizing them with the resize tool, or in the properties menu, doesn’t seem to work, although I wish it would.
