WRX Driveline... will it fit my TS wagon?

I have an 02 Impreza TS wagon and my driveline (aka driveshaft) is shot. I have the option to buy the driveline from an 05 WRX wagon, but don't know if they're the same. Has anyone else used a driveline from a 2.0L turbo'd car in their 2.5L NA car successfully?

I've searched the forums and other sources but haven't found a clear answer. Thanks for your help!
