I need to know the type of frt & rear differentials and ratio's that came in the 1982 jeep wagoneer ...

I only have so much RAM chicnman, there's only so much detail I can hold in this brain pan! I don't know the answer but I know someone who does. Call the Drive Train Doctors in Las Vegas, toll free at 1-800-216-1632, or visit them on line at http://www.drivetrain.com/dana44.html . That particular page on their site  talks about the differential for your Wagoneer. I'm sure they'll be able to get you the info and parts you need ...
Good luck!
