Does anyone know if parts from the last generation Thermador ranges are interchangeable with the current generation?

It would seem that some parts are compatible because the line did not differ very much. AAP offers parts for the last generation (PRG364GDUS). Some of the current ones are PRG366GH and PRG364EDG.

Some parts of interest are the spark ignition module, spark electrodes, oven igniter and broil igniter.

Thanks for any input.
