I have just bought an 86 22R 5 Speed SWB Base line and the front diff is gone, have about 1/2" of wiggle in PS output. Do I need to find a new case befor I pull this one or is that much play just in the blown diff and not in the case. I have found one with the Vac Disconnect off a V6 Auto for $175, will the case interchange? I have the service manual but it does not say, it does not even give gear ratios.I am a Mopar guy and my last Yotas was in the mid 90's. Had an 84 4x4 SR5 LWB and a Kal Kustom Streached 2WD Dually.
