1999 lets assume great condition and rear locker, 107K miles and the timing belt has been done (grey in color and front brush guard). Dealer wants $17500, I think I can get it for $16000. Figure if I do all of the fluids it should be good for another 100K without any huge expense. What do you guys think about the price and doesn't the 99 have the weak front differential or is that the 1998? How about the transmission shim, is that only a problem with the 2000? Thanks for any imput.
