How to straight Speedometer cluster in 1972 Dodge Demon?

Hi All,

I'm looking for direction/steps to partially remove speedo cluster and straighten/level the cluster in the dash. Its currently sitting on a slope. Is it as simple as removing the 4 screws holding the cluster in place? How is the cluster secured in behind? Attached is a picture of what I'm referring to. From the picture it looks like I may need to lower the tachometer down out of the way. Thanks in advance.
