Hey peeps

I've got a 2003 Civic SiR (as they are called in Canada), and I tried to order a dash kit piece on Amazon which would allow me to install an aftermarket stereo. There was no option for a Civic SiR on Amazon, so I ordered the one for the Si thinking... "how different can they be?" The piece doesn't fit by just a few millimeters, but clearly it's not the right part.

Here's the part I ordered which didn't fit: Wrong Part

1) What's the difference between the Si and SiR?
2) Where can I get such a part for a 2003 SiR? I can't seem to pull up anything on google!

Need. Tunes.

Thanks!
