I think that the Acadamy kit is for a LVTP7 not LVTP7A1 despite what the box and some suppliers state. The kit is a modified Tamiya LVTP7A moulding with the hull backdated to the earlier model. (The figure that comes with the kit is a dead giveaway as to it's origin.)
The most obvious difference is that the LVTP7 had the circular headlight assembly in the hull, whereas the LVTP7A1 had a rectangular assembly in cut outs right at the top of the hull plate.
There were other less noticible changes, see http://afvinteriors.hobbyvista.com/lvtp7/lvtp7a.html for a good history and detailed interior pics.
ROK have around 60 old LVTP7's and have built 42 AAV7's as a joint production venture to replace them in front line duty. See:

The kit you are building will be of an older vehicle and pics will be hard to come by as every pic I could find was the later up armoured version. Therefore, paint it what looks right to acadamy's own specs, and who is going to prove you wrong
Are you building OOB or did you succumb to madness, like I did with my Tamiya LVTP7A , and super detail it?
