I too got the Autometer 3'fer w/tweeter and it worked just fine. Factory paint is xlnt.
Got mine (and gauges) from Scheid Diesel (800) 699-1934. Andy was extremely helpful. They even provided a pre-drilled elbow for the Pyro probe, saving me the work. Andy even offered to PAINT the Pod with factory color for me! Nice to find businesses that still have "service" in Customer Service!
