Are the ABS rings the same on all Classic Impreza's or did they change them over the years?

I've got an MY99 UK Classic with a damaged rear ABS ring and I need to get a replacement, but I want to check which type I need so I don't end up getting the wrong one

TIA

 

anyone?

 

Hi I changed mine on my98 but changed the whole hub and they all seem the same

 

thanks
