I can't answer that at the moment but was glad to find this topic because I have the same questions. I want to put the 135K cluster from my 02 GTP in my 202K 99 GTP because the 99 needles are faded and lens is scratched. Will they swap? Did not know a Tech2 might be involved. For what? The 99 car's clear title says "EXEMPT" under odometer reading.
