Although it is likey his Auburn is the oem unit, he doesn't know this for certain unless he has owned the car for 4 years or more or knows the car's history. The manufacture date is in a code stamped on the unit case.

I had hopes that my Auburn would qualify but it didn't and I went with a slightly used Torsen out of a 2000.

 

Thanks, that was extremely helpful.

 

I bought a "take-off" torsen from SLP and used it when I replaced my 2.73's with 3.42's. I am assumming they replaced it with something better if they took it off and sold them. Don't know. Anyway, I like it.

 

How much was it and how long ago was this?

 

It was about 2 years ago. They had them listed on their website for $99. The reluctor ring for my ABS was $20.
