How well do you know your Prados?

Does anyone know when the various diesel engine/gearbox options were released on the 120-Series Prado?

I understand that the 120-Series Prado was released in 2003 with a 3.0L TD (same as the 90-Series Prado had) and a 5 speed manual gearbox, which continued until the end of 2005. It was my understanding that in 2006, the Prado was released with the D4D CRD engine and a 6 speed manual gearbox (as well as some other changes), which continued until the end of 2009 (after which time the 150-Series Prado was released).

I have recently seen a dealer advertising a 2004 model Prado with the D4D engine (you can see the D4D badges in the photos) with a 5 speed gearbox - I didn't think the D4D came out that early, or with the 5 speed gearbox.

Can anyone provide a summary of the model run, particularly the engine/gearbox options, or point me in the direction to find this info?

(Please don't suggest I ask on PradoPoint - I'm still waiting for them to approve my log-in that I applied for in mid-2009!)
