"Classic" UI Tab theme?

I'm trying to upgrade from jQuery 1.1x with the tabs plugin to jQuery
1.2 / jQuery UI. Given the look and feel of my project, the original
look/feel of those tabs were perfect. However, they don't seem to be
there in the new UI. Does anyone know where I might find the original
theme? I suppose I could recreate it on my own but I don't want to
reinvent the wheel.
Thanks in advance!
