Thanks for that link. Sadly, I have already gone over that list many times and cannot find the file I had used previously. The link had a couple of cross references for MoPar and Mercedes parts numbers, but no third party ID of parts.

As an example, the list I found previously had a MoPar and Mercedes part number for the Crank Shaft Position Sensor. It also had the original manufacturer - in this case Bosch, and the Bosch part number. Saved me quite a few coin on that one part. Suprisingly, the MB part was cheaper than the MoPar listing and of course Bosch was 1/3 the price of MoPar.

Is the document I'm looking for on your link somewhere and I just can't find it or is it gone?

Cheers
Henry
