I have the Panzer lll, Taigen metal lower hull and the HL upper hull. Any ideas on how to attach the two together. Magnets maybe?

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.

Yep, I have the brackets that came with the Taigon lower hull,I thought that because the upper hull it would not fit.

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?

Here's the instructions I have. I bought mine before there was Taigen. But, they are the same hulls.

here is the upper hull (HL Panzer III)

Compare the picture to the instructions in my previous post...

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

Thanks Erik, got it installed last night.
