Oven would not shut off

I removed all the burner heads with a torx driver & released the top of the stove by pushing in two clips with a screwdriver. I raised the top and located the thermostat as it fed through back of stove, then tied a line to the old thermostat to be used to pull the new one through. This did not work, so I removed a cover on the back of stove to provide more room & spread insulation apart so i could see hole. I was able to easily feed new thermostat through hole and reassemble.
