I would think you should be able to swap the stepper motors in the back of the instrument cluster. are the rpm and speed of the two dash readouts the same? Might be interesting to get two clusters and see if it could be done.
I was planning on running the complete 08 harness and pcm. Just use the original pcm for engine functions only. I would eventually like to put a 6.4 in as well but funds aren't available at the moment.
