HELP!!.......`93 250SX swingarm bolt

OK,I know this sounds strange,but how does it come out ? It`s got a nut on the shifter side that we removed,and what appears to be a captured nut on the other side.I dont wont to just force the captured side out if I missed something.I`ve worked on lots of bikes,but I never saw a swingarm with nuts on both sides!!!!!
Any help from someone who has seen this?

Thats what I thought,but it didnt budge and the last thing I want to price is that bolt.The word backorder comes to mind:p ! I just wanted to ask to be sure before I started really banging on it and it mushroomed!
