So I went about carpetting and modifying the rear draws / fridge system that I got from Mudski. In the end I ended up tapering the front upper area to suit the tapered patrol's rear draws. I carpetted the whole lot , and in the end removed the draw and little slide out table (which i can add back on at any time). I like it the way it is. Not a fan of the draw.

For a non carpetter and non carpenter I'm impressed how it all turned out.
