how do you get this dam screw deal out to take out the mast. i tried 3 different types of needle nose and no luck.. special tool or something. you know one of those tools thats cost $80.00 that you only use once
since your antenae is already broken off i'd try taking a deep well socket that fits tight and hammer it down onto the nut and then see if it'll grab ahold of it and back it off.
