Decent impact gun, vibration helps a lot. If no oxyacetylene, I like yellow MPS gas with regular torch.Wont get cherry red but often will do the job. Looks rusted in.
 

Or break it loose with a big Johnson bar after soaking with penetrating oil. Watch those threads if hitting with a hammer.

Thanks J/H. Are those washers on each side?  Why do they both have a hole in them?

in the one picture with the bolt showing, at the top right side looks like the metal brace has a crack in it

Looks like it, with an ex centric adjustment that locks against sheet metal lip. Mark where hole is, might need to go back in same spot.

Spray penetrating lube into the holes, should run in behind and help free up.

Try a cold chisel and tap it behind washer so it starts to separate from bolt.
