The Tamiya kit is definately a good one.
This is actually closer to a late 80's / very early 90's representation, by 1992 I don't remember seeing an AAV without EAAK. By the late 90's it had all been removed and put into storage (except for vehicles on a MEU, or operating in a "hostile environment", which is still how it is done today) because of excessive wear and tear to the suspension and drivetrain. The EAAK was also deteriorating in the constant exposure to salt water. The plain EAAK mounting bosses can easily replicated with strip styrene. --- Let me know if you choose this path, as I might be able to track down the drawings that show the positions of all the bosses on the vehicle. Don't get too wrapped around the axle about accurate locations because the techs who put on the real ones didn't either. "Hanging" EAAK falls somewhere short of fun on these contraptions.
Additionally 1995 saw the modification to SINCGARS radios which has an antenna mount added along each side. There are also smaller mods such as the EPLRS radio which adds anoth antenna mount on the starboard aft (the kit might have this, memory slips), TACNAV antenna forward of the drivers station, and PLGRS antenna port aft on topside of turret.
I'm not sure how many, if any, non-RAM/RS AAVs are still in the operating forces today. I can only attest to one ragged hagged wore out AAVC7 that hasn't been RAM'ed up in my unit. (RAM production started in 99)
If you need any pics of specific areas let me know, just a matter of remembering to bring my camera to the ramp.
