In a tight spot

[wold]

I've been trying to get a straight answer on what size ball end allen wrench I need to turn the truss rod on a 2011 MIA Fender P-Bass. Such a tight spot to get in.

Thanks.......appreciate the help. Finally found a manual for this bass. Every time I found a dimension it would have a question mark after it. Quizzical.
