All,
It's easy to read the part number while the old sensor is installed. Just need to be able to read upside down with a magnifying glass (for us weak-eyed geezers).
My 2004 has an original 037 installed and I am carrying a new 037 as a spare.
I'll be replacing the Crank Position Sensor and the Camshaft Position Sensor with new Bosch sensors, then carry the now working sensors as the spares.
That should carry us through until we become invalids (?).

Thanks to all for the never ending information and advice on the Crossfire Line.
Cheers,
Chooch
