i need to know if the rear splash gaurds are the same

 

CRX rear flaps are different than the others (sedan, hatch), they are longer. Not sure how much difference there is between 88/89 and 90/91, I know the bumpers are different though.

 

will the crx rears bolt up to the hatch?

 

Sure, you can screw them in, you can screw anything in. They won't fit though.

This is what happened when I tried to put EF9 flaps on my 91 Si.



and I'm 99% sure that the CRX flaps are longer than even the EF9 flaps.
