I have a guy at work that has a 92 cherokee he is parting out. The 4.0 and a NP231 TC he is looking to get rid of for around $500 for both. He said the motor had around 130k on it. Also parting out the remainder of the cherokee only thing missing is the transmission and the alternator was seized. He also has a 2wd auto transmission.
It is sitting about a 1/4 mile out the back gate of the sub base.
