ok guys, here is what I got and where I got it from. They had the gaskets and the o-ring, and the thermostat !! I also bought an O2 sensor from here as well.

These parts are for a 1992 SSE, but I bought the same ones for my 97 SSEi and they fit perfectly on both cars.

These will fit from 1992-1997 and maybe some others. Yes, you need both gaskets.

Part number Item Cost

45848 180 Thermostat 6.44
35486 Water outlet Gasket 1.86
35534 Water Outlet Gasket 1.62

The O2 sensor for the 1992 only is an AC Delco #213-503 and costs $31.49

They were very helpful and fast and answer questions via email.

Cheers,

Andrew
