AC Engine thermostat housing?

[pjbowman]

Is there any source for replacement thermostat housings for the AC engine? Mine has a chunk of the inside 'lip" where the thermostat sits missing. I am assuming this let coolant past the thermostat which is why my engine always runs cool. The thermostat itself seems to be working fine.

Have reahed out to Robin Woolmer, looks like the ones he has will do the trick and take a modern thermostat also!
