I'm not sure about the model of transfer case? I was thinking of reusing the stock one out of my 89 and also replacing the clutch and the rest of the usual stuff related with the clutch while everything is out in the garage. About the sending unit? Can I get a 19-gallon tank like they use in the 91 Jeep Sierra and put it in my 89 without very much trouble?
I Think I will have plenty of more questions when I get into the project. Thanks for your help and this is the best Jeep website I have found, all the other websites IÆve asked questions on nobody would answer back or they donÆt have the knowledge to answer back.

Thanks again
