Let me know if you're interested and I will check it out.
I've also got a quantity of those carb gaskets with the four notches though I'm not certain they are the correct size for your application.

hi motto

That is a generous offer !

I will see how I go ....

I might try making a thermo housing with a BSP threaded fitting . Aluminium would be OK to use for this job . BSP fittings are ubiquitous and most hardware stores have stock .

The lower hose is 1 3/4" I think ?

When I pulled down this 216 engine, the original brass bellows thermostat was still in situ with a 1940 date on it , stuck in the open position . The new thermostat I put in , in 1998 , has corroded away and collapsed .

BTW these new aluminium radiators are prone to corrosion by a chemical/electrical reaction. The coolant can act as an electrolyte and the whole thing turns into a battery ! Good grounding is required to reduce this problem .
