I only saw guys breaking track on the bradley once, but it looked like a decent sledge hammer and a big punch were the biggest tools. We ended up with a spare pallet work of track pads after the Bradley was unexpectedly taken in for reset. those were just standard big bolts. not sure what the M113s are. I imagine if you ask around 25th enough you'll find someone who has a set sitting back in a tool room somewhere. That or if they have a FRSH, it should have the tools, I think.
