Alternator XJ 97...need advice

Hi

Stock alternator on my XJ 97 Sport 4,0L has passed on.
Need an advice for a new one:

- Is it the same alternator on all 4,0 L Jeep models from i.e. 91-2001(bone yard hunting )
- Where to buy without core charge(international shipping)

Thanks in advance

97 had a 90 amp alt
sometime in 99 the switched to 124 amp alt.
but i believe all the denso xj alts should physically fit. but i believe the wiring was slightly different in 99 on. mike
