Are you sure about the chassis and engine numbers?

Try Jurawan's in Diego Martin for the thermostat. I changed the thermostat in my 4g13 engine (CK1 chassis) a couple months back and that was the only place I got one.
It was not the exact temperature rating (but was close), but it fit without any problems and so far I have not gotten any overheating, or over-cooling issues. The temperature needle is pegged at a slightly lower reading on the gauge than what I got with the previous OEM thermostat.
