Was wondering if anyone would have the part number for the inner most sealing ring for the input shaft on a 42re transmission? I have read that the selective snap ring originally used was prone to crumbling and there is an updated part for it. 1996 Jeep Grand Cherokee 4.0L 4x4. Thank you for any help!!!

 

If anyone is searching for this part. The two input shaft sealing rings are actually the same part number now. Here is the part number if anyone needs it 1401221AB.
