I am looking to retro fit a load cover and have followed the helpful instructions posted by NikpV in an earlier thread about speaker replacement, to remove the rear quarter-panel. Got it off safely, nothing broken.... yet! Anyway, I can see the markings on the back of the panel where I need to cut out to receive the brackets but I have two questions. Firstly, what it the recommended method of cutting the panel - I have visions of the material on the front snagging and laddering. Secondly, I think I need something to fit between the bracket and the car. The bracket has two screws which are horizontal but the car has two holes, one larger than the other which are vertical (picture hopefully attached). If as I suspect there is a bit between the car and the bracket, how is this fixed in place and will my Ford or VW dealer have this for sale? Thanks very much. Pal
