Parts numbers for Oil Cooler Mounting Plate O-rings?
 

Does anyone have the correct part no.s for mounting a late oil cooler on the very first 2.5L engines with the different munts? I'm specifically looking for the correct o-rings.

I've been in contanct with three vendors so far and the response has ranged from confusion to ridicule :D

I don't remember the correct o-rings, but to mount a later oil heat exchanger on a very early M96 you need an adapter plate like this:

Try contacting one of those vendors and asking for the correct o-rings to use with that. I'm pretty sure that the top side uses the standard later model parts, but not sure about the bottom. Maybe I'll find my old invoice in email.

Here's a couple pics from when I was playing with that stuff:

Here's what I found in email. I'm pretty sure that it all worked with those o-rings, but that was a few years and many cars ago.

Thank you for your help.
I Just got an email from a dealer which contained the actual bullentin from Porsche. I'll upload it here for future reference.
