Best way to attack exhaust spacer bolts?

So I’m attempting to install exhaust spacers on my 2012 JK and it’s proven to be a pain. Got both bolts off on the passenger side. The driver’s side is giving me issues. I snapped the head off of the bottom bolt (easier one to get to). The top one is stuck and I can’t get my breaker bar in there. What’s the best way to get the top bolt out and remove the snapped bolt in the bottom?

Both are pretty damn rusted too
