Panzer III question
#2
It should have come with brackets and instructions. There is a bracket in the front that you screw into the front post and "clips" that screwed into the back two posts. See the parts in front of the hull in the photo.

You should just be able to screw the lock clip in the front to the upper hull and near the rear posts you add the locking clips for the lower half. Could you take a picture of the upper hull for me?

Yea looks like you should be able to direct bolt that just like in the instructions. The front clip attaches to the front of the top hull and the two clip like things go in the back facing outwards. They will lock into the rear of the chassis right in front of the idlers. If you look close on the outside of the hull you can see a slot where they fit in. You just need a flat head screwdriver to open the hull. If you still need help just let me know
