[Healeys] Thermostat runs with blanking sleeve

You can run the Moss blanking sleeve with a thermostat. 

I had cut away the blanking sleeve except for the part necessary to cover the bypass port. I ran it with a 180 degree fail-open thermostat and 2 Moss rubber gaskets, one of which had the hole slightly enlarged to accommodate the increased thickness of the thermo plus blanking sleeve. 

Separately I had bought the BCS 160 degree robertshaw with soldered ring blanking sleeve. I modified this by replacing the t-stat with a 180 degree robertshaw with their ring soldered on. I'm now using that because the robertshaw has a much larger opening than the Moss fail-open.

The blanking sleeve has a small lip that sits in the same recess as the thermostat. ?Not sure both the blanking sleeve lip and a thermostat together will fit and seal the cover correctly.Mike MacLean

I wonder if you could combine this with a "standard" thermostat to
approach the original with the sleeve?
