DAVID: As Mintee says there is a very small relief in the Chevy rim, so small that I didn't spot it and drilled experimental holes on the first attempt.(Meziere themselves advised me to drill two 4mm holes in it)You can see it if you hold it up to the light.
PAUL: If you are using the British housing them you have to be careful if using a different thermostat to the one supplied. If the new 'stat has a thinner
profile around the edge then it may allow coolant to seep through when it is closed, I did say, several pages ago that it might be necessary to use some sealer on the rim. The Meziere housing comes with a gasket which sits over the rim of the stat so there is no problem there.
