Rear trailing arm bushes

[Jack]

Hello all, 

I've got to change my rear trailing arm bushes again. I've ordered some that have arrived but they look different to the ones I purchased a couple years ago. The website states that they are for a mk1 crv but I don't understand why they have a different shape?

Not sure why but will they fit even though they look different?

If not, then return them for the right ones
