1997, 1998, and 1999 production are considered early model production when regarding the rear brake set-up.
2000 and up are considered late model production regarding the same rear brake.
If you install an early model rotor on a late model rear the rotor needs to be shimmed to work properly.
There has been some discussion regarding the rear wheel (early and late model) and how that affects the rear brake (rotor acceptability) but there has been no definitive answers to that question.
There also has been some discussion regarding the caliper mount (early and late model) and whether there is a difference between the two models that would affect the rotor placement but again, there has been no definitive answers regarding that question.
I would suggest to try it and see how it works.
I am sure the forum would love to have a solid and correct answer to you question.

All one has to do is to check the HDL (or other) parts fishe to see that there is only one part no for the caliper plate. Therefore it is definitive. Old wheel old rotor fits everwhere. New wheel new rotor fits everywhere. Mix and match=problems....ie shims
