You probably have better luck asking this question in the civic section.

they do not bolt up !! you will need to fabriacte a nolt set for the rear bolts.. Quick fix is putting a piece of wood to balance out where the bracket bends and doesn't bolt it becuase of the bend. I sat in a wobbly integ seat in my 90 hatch for a while. then i blew the motor.
