side locker help

2011 puma defender 110 5 door (was a 7 seater) I am struggling to find a side locker for this model. Lots of side lockers on ebay and lots of other sites but I am darned if I can find one to fit this vehicle.. Best I have come up with was one site that said fit to a Puma at you own risk NOW FOUND ONE JUST THE JOB FROM LRSPARES. I WANT ONE TO FIT THE REAR BODY PANEL JUST ABOVE THE EXHAUST PIPE TO TAKE A SMALL PROPANE CYLINDER AND A PORTABLE COMPRESSOR BOTH FOR EASY ACCESS

What do you mean by "side locker"?
The one that fits in the rearmost pannel giving access to the load area.
