Probably a major headache. The motor and transmission mounts will probably be different. And, the driveshaft will probably be different length and not sure if the U-joints dimensions are the same size. Next is the problem of the sensors for the motor. Your 99 PCM will not like the Jags sensors, thus you will have to use all the Ford V-6 sensors which will require some sort of adaptors to mount them on the Jag motor. And, you will require a new tune if one was an auto and the other was a stick shift.
