just wondering,

are all the h3 gauge clusters the same? do any of them have added features? i replaced my friends OEM yukon gauges with a gauge set out of an escalade. it plugged right in and added a trans temp gauge, chrome bezil and chrome needles. i have plenty of idiot lights but an actual trans temp gauge would be nice if its an option. Also do any h3's display fuel mileage. If so where is it displayed? It would be nice to know which tire is low and not just that a tire is low.
