Here's a trick with this kit listed above. I've tried installing these all kinds of ways on three different Cadenza's ( one base model and two premiums ),,,, You'll find it is very easy to get three of the bolts in place, it's that fourth that is a little more tricky. The reason is the angle is slightly different. I install the front two bolts first because there's less room to get to them. Then the rear closest to the door. Then you have a ton of room for the last one,,, just simply move the seat all the way forward,, there is a small bar running horizontally under the front part of the seat. Cut a scrap 2x4 or anything else you might have laying around just shy of this bar, and the area under the back seats. Slip the 2x4 in there then use the control on the seat to move it back just a smidge, DO NOT GO CRAZY - you'll burn the motor up. That will hit the bar, and correct the angle so it is very easy to get the last bolt in there. Hope this helps you all. I may be back on later and snap a photo so it might be easier to understand what I'm talking about. After installing these several times this trick will help trust me.
