Looking at replacing bushings on the rear suspension crossmember. Any way to do this without removing the crossmember?
This is a case where you would be better off asking at a forum dedicated to your type vehicle. Google “Nissan 300zx forum”, lurk on a couple of them until you find one you like and then join. Also, while lurking (visiting and reading without joining), you might use the forums search to see if that question has already been brought up by one of the members.
