I'll get myself an Impact driver set like suggested anyways as its a good tool to have on hand I'm told. And if it does not work, then I figure I'll spend some time cutting up the alum chocks from around the bolt and then cut the bolt off flush with the top of the bow plate... which upon further pondering, I am not sure if it's Al or a cast white metal of some sort..
the job'll be done when the job is done.
