If they're the ones from Vietnam, they don't fit as well as the originals, but you can make them fit reasonably well if you have mechanical skills.
I bought a new rear one cheap because the guy who originally bought it said it would never fit.
I crushed it in about 10mm on the width using a carver clamp and two blocks of wood.
Made me cringe a bit, but it didn't buckle or pop the welds.
Fits perfect now.
If you're a fussy type and you want a perfect fit straight away I'd suggest you find genuine Honda parts
