You have a 90 degree thermostat that was manufactured in February of 2007. Any 90 degree thermostat that fits should work. Be sure to get a new sealing ring along with it (Many thermostats don't come with a new ring).

This is something you'll want to spend the extra $4 or something on, and go with an OEM one. Some of the aftermarket ones can fail in the closed position, and your engine will not last long without being able to use the radiator.

I just priced a t-stat from local Volvo dealership; they want $30.00 for it. Autozone is $12.00 + $1.99 for O-ring. FCP is $12.00 —but add $9.00 for shipping. Hmmm. What to do?

I can only add "+1" to jablackburn's comments above. A non-OEM thermostat may not be the quality you need for such a critical part, and if it fails it can cause a lot of damage.
1997 855 GLT (Light Pressure Turbo) still going strong. Previous: 1986 240 GL rusted out in '06, 1985 Saab 900T rusted out in '95, 1975 Saab 99 rusted out in '95, 1973 Saab 99 rusted out in '94

It really is worth the cash for the OEM t-stat. Cheap one failed closed on my 240 and caused a lotta damage. Extra few bucks on OEM to save possible $1000's is worth it.

No rubber ring on thermostat(busted) when I removed, just the flat rubber gasket that stretches over and on to gasket edges. There is a rubber O-ring, with my thermostat kit that fits perfectly into lower thermostat housing. Should this go under the thermostat between thermostat's rubber gasket and aluminum housing below?
