Front panel spot welded to bedside?

[Mack B]

Has anyone ever ran into this? I’ve got other bedsides here that wasn’t and I’ve never heard it mentioned here.

I’m attempting to remove the bedside.

I’ve 100% positive I have every bolt loose. I can move the entire bedside other than the front. I can even wiggle the very top of said front corner. As well as I can see into that gap I can see about 5 divots that are possibly spot welds? Between the second and third bolt. I can’t see any marks on the inside of the bed to make drilling easier.

I really wanted to disassemble rather than pull the bed whole because of space issues. Any ideas for something I could use to break the spotwelds. (Im picturing a really long putty knife) or perhaps I could swing the bedsides around from the back and see if they break? Open to any idears.
