Should work other than VATS will have to be turned off.

If both cars are automatic yes.
Vats will be a problem, if you are asking this I assume you don't have tuning software. If that's correct then vats will be a problem. I don't know if you can do a vats relearn using the 30 min procedure with a 98
It's worth a try

You will have to change the vin in the pcm, and the vats will have to be relearned or deleted.

Without the right Vin, your radio may not work and your air bag system until you do put it in..
