1941 Pickup Gauge Cluster, Remove Needles?

[quik]

I've got a 1941 Pickup with a stock gauge cluster, and I would like to remove the faces from the gauges to do some cleanup work. My question is, how do you separate the gauge from the face with the gauge on one side of the face and the needle on the other? Can I just pull the needles off the gauges (carefully of course) and then unscrew the gauge from the face?
