My solution to the lack of 333-180 thermostats came when I ordered a pair and the vendor sent the wrong ones,330-180s. Studying the hat on the 333-180 I discovered that it is a simple press fit. I gingerly removed the hat and pressed it onto the 330-180. Problem solved. This was 3 or 4 years ago and no problem with overheating.
