Here's a sketch of the jack holder. The jack itself slides into a wooden pad that sits in this bracket. I have a scale-able photo but haven't attempted making one yet. By the "bins either side of the jack holder", do you mean the two metal boxes on the rear deck (approx. 6" by 4" by 2") that sit on either side and under the battery box? I'll draw up the Boys centre bracket (the one right under the battery box you speak of) and post the results.
