I am wondering if it would be possible to switch from a 4 guage cluster to a 6 guage cluster? Would it be a drop in replacement? Would the odometer be accurate? Would it be plug and play?

4 guage cluster that is installed currently: Mopar Part Number 56049571AB or56049571AA
6 guage cluster that I wish to inquire about: Mopar Part Number 56045646AJ or 56045646AI

 

I would expect that the odometer would reflect the mileage from the donor vehicle. As for if it would work or not.... That, I really don't know.
