I have a 2002 WRX, and was interested in adding the following to it from the 2003 models. Does anybody know if each of these things is feasible, and how much it might cost?

1. Sunroof and switchgear that comes stock on 2004 model.
2. Kit for heated mirrors (with stock switches)
3. Gauge cluster with center mounted tach and silver trim rings.
4. Deicing wiper with stock switch.

I don't even know if it's possible to get these things, but if anybody knows, please lemme know.

Thanks.
