Hi Tim,
I fitted a 12v Clayton to my 1950 TA about 3 years ago, it is a great heater. I used gfn T’s and fittings and an inline T/Stat in the top hose beyond the heater T.
There is a control valve in the flow hose which has a Citroen based control below the dash. I used a Smiths rheostat as a switch and fan speed controller.
I remove the T/Stat in warmer months as a precaution.
