No problem. You did more for the OP to understand what he needed than the other posters. I cleaned the thread and hated to take your post down but to be fair to all they all had to go. I have been chatting with the OP through a pm. I don't believe the question has ever come up about a part number on the D4B's. Mopar didn't sell them over the counter like the LD4B's. That's why the LD's had a Mopar number. Thanks
