73-75 Gauge Tachometer

Quote:
73-75: Amp gauge instead of volt gauge. This cluster will only work for these three years only and are NOT serviceable since they are completely sealed. Just plugging one of these clusters in a 76 and up truck will result in instant meltdown upon turning the key.
So I was reading the

73-87 Factory Tachometer Information
page and was wondering why a meltdown. I have a 73-75 Gauge cluster with a tachometer and wanted to see if it is possible to put in my 79. Would the meltdown happen because of AMP gauge instead of VOLT gauge in earlier models? I figure the tach has nothing to do with it, correct. So can I just change AMP to VOLT and be okay hooking up cluster to 79 truck?
