I have a 1999 Dodge Dakota 3.9L Automatic 4x4, Extended cab. I have been looking for a 231D transfer case with a very specific 5210 5316 part#. Apparently these were only made 2 years. I live in Southwestern Ontario Canada and have looked everywhere to no avail. I cannot have mine rebuilt because the casing is cracked everywhere which means i also have no core. If i can find a T case with these numbers working or not that would be great and any help would be appreciated.
