JDM Blobeye

Sooo after doing tons of research on JDM Legacy Wagons I decided to start looking for one in Japan auctions, well I ended up getting a 2002 Blobeye WRX and is importing at the moment lol, technically its a 2003 but manufacturing date is 2002 i assume. Now i know there are many options out there available to me in Canada for Blobeye WRX, however Blobeyes were produced in 2004 in North America. So basically i am wondering will my car being made in late 2002 and JDM affect the fitment/compatibility of the parts for a 2004+ model? Or is there at least a list out there that has the cross fitment/compatibility of the car? Really any information i can grab will help
