The olive green one is the only knee board cleared for use in FJ, and there is a mod to fix the issue with the rivets; however, is it really fit for the job?
Working with an OEU recently, they alluded to the fact that most use a privately purchased alternative knee board - if that is the case, then highlight the fact that the current one is C$%^ through your FSO or SEREO and get the kit changed.
