At this point I'd suggest getting a new T61, rather than replacing the dock on a 5+ year old T30.
Even if everything in your notebook is still working fine right now, the components are definitely getting closer to end of life. I'm also sure your display is quite a bit dimmer than when it was new, as I know my T41 at home is much less bright than my new T60 at work, and the T41 is about 5 years old at this point. Plus your battery probably doesn't hold nearly as much charge as it used to, your hard disk is tiny, etc, etc.
A new dock for your current computer would almost certainly cost more than the entire T30 is worth.
