i found it actually easy, just time consuming-especially with the wiring...
i have a few pics when i put 4 auto meter pro-comp gauges in mine.
peace of mind having functioning gauges
ground the bezel to fit the gauges

cut off the 4 gauge section
re-routed the wires i need, went to the stereo shop & got a multi-plug for the gauges so i can still take out the dash
finished
