The Mopar one is an Autometer pod.
The a-pillar piece is cheap if you need to replace it and easy to remount.
You're going to need to mount the gauges somewhere, and this is the least destructive way of doing it. Cheaper than replacing a holed up dashboard or some other very large body panel.
My 2 cents.
