Monessen Thermocouple Removal

As the title implies I am having a heck of a time trying to figure out how to remove the thermocouple from the housing that holds the pilot, igniter, thermopile and cthermocouple. I have removed the bottom nut from the original thermocouple and I thought that the unit would just drop out of the housing. It doesn't... Any ideas as to how to remove it?
Hope the link to the pic comes across...

That link is to a private picture. You'd need to set it to public or you could post it directly to the board.

A model number of the unit you are working on would be helpful too.

I have seen some assemblies where the individual components like the thermopile are not intended to be removed. You replace the whole assembly. I have been able to remove those non-removable ones by bending the metal tabs holding the thermopile in place.

A Majestic stove. Looks like a 28D0400 thermocouple. Yours may be welded in there from the heat.
There are some styles that can actually mount in the plate.

So ideally I should just be able to pull the thermocouple out from the bottom? Do you think some heat from a torch would un-seat it? It appears that that is the last option I have...

A torch may help. You'll probably need to turn the old piece out. It will be damaged in the process.
