Looking for a 259 V8 headbolt for a '55 President. 3 7/8" long from top of cap to bottom of thread. It's the #4 bolt in the tightening sequence. (Hoping I can get the threads out of there before I get the new bolt- not looking forward to it. When I went to loosen it, it snapped ) Thanks for any info. Feel free to pm me if you're willing to sell a bolt or reply to thread. All appreciated. Thanks for the help. Any tips, tricks, or other info about bolt removal also very much appreciated.
