***Pic' Request*** 172 backbox mount

Does anyone have pictures of the mounting points of their 172 backboxes? Since I had my new backbox fitted last week, it has slowly started to sag and drop to the right again. I can tighten the clamp but I think the problem will re-occur.

I have seen back boxes with two mount points, like the one below.
But where does the mount on the right mount to?

Any pic's would be great.

It connects to the mounting plate thing that the exaust is on top(in the pic) of then the biggest rubber part connects them together ill get a pic later
 
what you do is remove the reno clamp, then a second clamp (shown under the the tailpipes) is sandwiched between the car body and the reno clamp.... if that makes sense lol

So the plate on the left bolts to the 13mm bolt at the back of the boot floor. The clamp on the left then attaches to the plate with the circular rubber on the right inside creating the 2nd mount?

Am I far off?
 
remove the reno mount off the car, has 3 bolts iirc, place the magnex one over the holes, then refix the reno mount over the top
 
So what is the purpose of the plate then as it just sounds like a spacer?

That has confused the matter of the right mount a little now. I thought the plate was some kind of secondary mount you added.
 
look at the pic, the plate has a bar that runs under the tailpipes. When fitted to the car,this bar runs above the tailpipes to the mount on the box you arrowed
