Richard,
Unfortunately that plug doesn't exist on my engine, the picture you posted must be the 2.25 ltr.
There is a garage near here, "British Auto Restorers", They have located for me the correct NOS bellows type thermostat and it's on the way, and they have suggested I could put a temp sender into the top radiator tank rather than drilling and tapping holes in the thermostat housing. I've not seen it done that way before but I can't see why it wouldn't work. They assure me they have done it to many an old MG and Austin that have no provision for a sender on the head.
Opinions on this please?
To that end I have ordered a dual Temp and Oil Pressure gauge so I can keep a close eye on what the engine is doing.

4bee I bet it won't be long & you'll get fed up with the hand brake lever up your trouser leg but that can be replaced by the later bent one & it is easier to get to, especially if you install seat belts.
Best wishes for a great resto.
Thanks 4bee for your well wishes; and I have a bent one tucked away for just that occasion... [bigsmile1]
I would still like to know if the "213574 - Thermostat Switch for Choke Warning Light" at the rear of the head would serve as a temperature light switch??? Of course I've no idea what temperature the switch is rated to so it may be useless for that purpose...
