Removing threaded extension on Budashnozzle1.0

I had a problem similar to other users with mangled threads on nozzle after not removing easily. Now I need to replace the threaded extension as well as the nozzle. However, I cannot get the threaded extension to remove from the heater block. Any ideas or suggestions? I am almost ready to replace the whole Budashnozzle, but would like to avoid it if possible.

Thanks.

Hmm, does your Buda look like this? https://reprap.org/wiki/Budaschnozzle/1.0

Are you sure it’s a 1.0, with a nozzle like this? http://download.lulzbot.com/Budaschnozzle/v1.0/Nozzle.PDF or does the nozzle look like: http://download.lulzbot.com/Budaschnozzle/v1.1/Nozzle%20V1.1.1.PDF ?
