Hi i have been on a hunt for a new oil pan for my 89 truck. The part number off of the inside of the old pan is 3914403. I typed in that number and was able to find that the old number was superseeded to the new number 4429403. This part new cost about 450 bucks where as a 94-02 oil pan only costs about 109 bucks (part number 4089093) I was wondering if their are any differences in the two pans and if so would the 2nd gen pan work at all??? Any input is greatly apreciated.

i believe they are interchangable! but dont quote me im not positive!
someone will know!!

 

I hope they are. Thank you for the reply, I called Cummins of CT and had them look it up and the guy on the phone was stumped. He couldnt find any of the origonal part number and didnt know about the superceeded number.Anybody ever tried anything like this? I want my truck back lol.
