That part number was on my invoice in 2006, so I am not sure about the accuracy today. I would call the tech line if you had question about the correct application.

Finally got a hold of a guy at Randy's ring and pinion who says the correct part number is the 911A342 for V6 models and 911A445 for 4 cylinder models. He mentioned you can run 342 either way, but you would need a bearing kit to modify the 4 cylinder diff. Eaton Performance has replaced the 342 part number though which might affect someone's searching. They now use part number 911A644 in place of 911A342. I hope this helps somebody out there!
