1998 vs 1999 XJ Differences

[s1xty7]

Are there any physical differences in composite or cast dimensions? Could one be interchanged for the other? When doing a brake job, is one better than the other?

Thanks. First I've ever heard of this change.

Also, the miles don't scare me. I'm just looking for the lowest miles to maximize the overall life span. If I can pay the same approximate price for a 200k jeep as I can a 120k jeep, I'm likely to go with the 120k jeep, all other things being equal. Takes a little more patience but should pay off in the end.
