Do a google image search and you will get lots of referance pics.
For EEAK sets, there are the Hobby Fan sets. They are rediculously priced though. One is just the mounting points, the other is the actual EEAKplates. You don't need both, either the full set for EEAK or the mounting points if you want to model it with the EEAK removed. As I said though, they are rediculously priced at about $100 each. Guess Hobby Fan thinks their stuff is made of gold or something. Way too much for me.
Another option is to find a Trumpeter or MiniHobby AAVP7A1 w/EEAK. The model itself is junk since the hull has been modified for motorization. The EEAK is usable to add to the Tamiya kit though. I am doing just that.
Here is an article by Vodnik that shows the Trump EEAK on a Tamiya hull. Has links to reviews of all LVTP7, LVTP7-A1, and AAVP7A1 kits too.
