I tried with the flat head. NO GO. I didn't want to destroy the bolts. I am looking to replace them with manageable bolts if possible. In the mean time, I am going to the store to get the tool designed to remove them. I don't have the assembly with me, but I want to get the tool and the replacement bolts.
HOW about the name of the style head that is so I can shop for a Tool? saftey 5 star anti-tamper a-25 or something like that....
