The only HQ seat separators I have seen use the same rear mount as a console and the front has a single screw straight to the floor. The few factory HQ consoles i've seen also have screwed straight to the floor with holes just in front of the shifter. I honestly hadn't taken great notice that HJ and later are different to each other too. Looks like I have some more work to do in this area. The HJ ones I have pictures of are all like the very top one in this thread. HX-WB are like the second picture in all my photos.
