Yeah, sorry, it appears that physically the mount face is oriented differently, the KJ CRD part number is 05142601AA.
If you look at this JK one for sale on ebay UK you will see the difference is in the mounting attitude and the way the inlet port points. Functionally I think they are the same: sealed units, sensor in the side and the outlet ports.

I think they are actually made by Behr tronik in Germany, but George at VM Specialist UK should have them or be able to get them.
Could you drill it out, I don't know.
I have a spare KJ thermostat as a contingency for the day I need it, and maybe JK CRD owners need to consider holding this in their parts box for the day they need it or change it at some regular interval before it goes, as they all do eventually.
