Replacing transfer case in 1991 Aerostar AWD

[eeess]

Can anyone tell me what is entailed with replacing the transfer case in my 1991 Aerostar AWD with a 1993 transfer case? Maybe drive shafts or transmission extension?

Thanks,

Thanks for the info. Someone pointed out that the '91 uses a gear driven speedometer while the '93 has an electronic sensor. My vehicle has an electronic dash and I'm wondering if the sensor signals may be
the same.
