I'm working on a 2002 Audi A6 Quattro 2.7t. I'm looking for interchangability for the following two parts :

Engine Oil Cooler - The plate that goes between the engine block and the oil filter.

Transmission Cooler Line - goes from the passenger side to the drivers side and passes right in front of the Engine Oil Cooler.

I've done a lot of looking so far and the oil cooler part seems to be similar to the ones on the A4's and A6's, and very similar to the 2001 models, but it looks like it is a different part number?

The transmission cooler line I'm not able to find anywhere - Does it interchange with 2000-2001 models, or is it something new that was introduced in 2002?
