Restoring iCal from Time Machine/Older HD

SO here's the deal. I upgraded my harddrive in my MBP over the weekend. Doubled it size to 500GB joy! What I decided to do once I got a blank copy of Lion on it was to restore just the user info, system settings and "other files" from the Time Machine back up I have (not from the old hard drive). Allowing me to install only the Applications I would really need after all my user info was on the computer and clearing up some more space.

This worked GREAT!

When I opened my iCal I had duplicate calendars. So, I deleted some of the duplicates. Apparently I deleted the wrong ones, and now ALL my calendars are gone. And before you ask, no, I didn't setup my TimeMachine (I decided to test things out before erasing that backup and start fresh with my new system)

BUT, I still have the old Time Machine backup AND I still have my old/smaller HD hooked up via USB.

My question is, where can I grab the iCal info from (Time Machine or my old HD) or do I need to start the process all over again just to get my calendars back?

Thanks in advance
