I have for sale a NP231 J removed from a 1998 TJ Jeep Wrangler 4.0 5 speed ax15. This Tcase has a SYE (slip yoke eliminator) already installed on it and come with a 19" long drive shaft that has been balanced for it as well. The SYE and drive shaft where only run 2 trips so they are not worn out or old. Asking $395 for the whole set up.
If you would like to contact me call or TEXT 419-343-9017.
I can send pictures.
