hey guys! can u help me with a part code for a radiator?

in online catalog i can find two codes:
1640050350 and DRM50095
but none don't match the one instaled on the vehicle.

gs430 2006 north america version
vin: JTHBN96S865000801
thank you in advance for your help

 

From my search of a US GS430 radiator, it calls for a part number 1640050340

Also part numbers will supersede another, they may update a design and the number will change.

 

thank you very much for the info. that was the serial no that I was looking for. I ordered from ebay, should arrive sometime between 15-25th of may.

best regards!
