I did forget about that, thanks for reminding me. I wonder if the tach element can be added from to the non-tach cluster to fix that issue. I should have thought about the mileage thing, a friend of mine got into the Lightning trucks and had a similar problem connected with the PATS security system and a dash cluster in a 2001. I think the final solution we came up with on that one was to disable the PATS system so the secutiry system itself wasn't shutting off the fuel pump and preventing it from running. Not sure how the Mopar system works, but you are right, there have been other times clusters were changed on the newer cars and mileage is one issue, but can't remember if there was any shut-off issues for security reasons.
