It’s out!
The bolt was cut in half using a combo of angle grinder and hair hack saw. The bolt head was still totally stuck so drilled into this carefully to remove the thread just in case the bolt head located onto a collar on the swing arm. Once this was out it looked like photo 1 however the bolt head was still stuck only now with a hole in it!
More heat and a drift that was just smaller than the hole in the swing arm and a few swift taps brought it out.
The bolt thread left unscrewed with fingers!
So now need a new bolt from Ducati and we can resume putting it back together. Will get a spring ordered later and take it back apart once that comes (spent a fortune on my other Italian mode of transportation after ignoring parking sensors and reversing my Giulietta into the wife’s Focus. Alfa bumper replaced and not a mark on the Ford)
Thanks again for all the help.
