Hello All.

I'm hoping somebody here can help me, as I'm totally lost!

The back box on my partner's civic is blowing, and needs to be replaced.
The issue is, I have no idea which backbox to get.

It's a 2000 civic 1.4 sport, 3 door, however the license plate parts sites keep telling me it's anything from a 1999 civic 5 door sedan to a 2003 civic coupe.

I know the chassis is an EJ9, but I still have no clue what backbox to get.

The most likely one so far has a part number of HA227, but it still doesn't narrow it down much.

Any help at all would be appreciated. I'm at my wits end!!!
