Are the thermostat housings the same for the 1l carb and the injection models?

Hi, I have a 1l carb k11 and the thermostat housing pipes are shot. I don't seem to be able to get a new one anymore so it looks like second hand is the only option.

Could one of you amazing folk tell me if ther are the same for the carb and injection models?

Thanks so much for your help!
