The one dimension missing is the minimum depth at the centre post which just has to clear the rear basket. This is 44cm. The depth at my post is 48cm, but the minimum in the description is 50cm. Based on the pictures I took a gamble and won. The instructions are a little brief but any experienced flat packer will work it out. I got the door brackets in the right way 3rd time. Still don’t know what the door runner adjustment is for. The cantilever link arm between the side and rear baskets can be adjusted, but this is not mentioned. If your baskets clip then move the rear bracket over by changing the threaded screw hole used on the rear frame.
