Pioneer tool mounting

After an impulse eBay purchase, I now possess the mounting brackets and straps for putting the pioneer tools on the tailgate of a series 2a.
I can see where some go from various pictures but there are some brackets that I can't tell.
Does anyone know of a diagram or/and some detail pictures? Particularly of the centre screw mount for the pick head as there seems to be something above it that I can't see on the picture I've got.

try this might not be much clearer ,shovel on mine had loop blade went into Google Image Result for http://lightweightlandroverclub.org/phpbb/download.php%3Fid%3D4149%26t%3D1%26f%3D8

Thanks, I'll have to try and get a collection of photos and see if I can work it out.
