Here is a great post on dash gauges then I have a questionafter: I have taken parts of several trucks over the years and lost track of what I took from which. Now, as I try to put my instrument cluster in my 47 truck I find that the tabs on the cluster housing do not line up with the studs that they are suppose to line up to. The speedometer cluster lines up perfectly but the insturment cluster bottom tabs are way too far apart for the studs. To confuse matters further, I have a second speedometer housing that also has the tabs further apart than the one I used. So, am I right in assuming that I have collected a housing from a later model? Enlighten me, please.
Interesting ; I have lots of old junky gauge clusters and they all interchange but you may have a '54 cluster there or one from a Dubble-Dutti van (P-van , forward control like a bread truck) as they used similar gauge clusters except they were 12 volts from 1955 onwards.... As it turns out , the '47 gauges had shorter needles and were painted red to boot , this made them harder to read at night so GM dropped that pretty quick . Most of that you quoted looked pretty familiar to me....
