Hey Folks; My wife wants me to switch instrument clusters in her 1979 F-150 (I don't know if the cluster in the truck now is the original or not) !! They are both D6T clusters but the cluster in her truck now has all 4 gauges (temp,fuel,oil pressure,charge-discharge meter), currently we aren't using the oil pressure gauge (we're using actual OP gauge) and the charge-discharge gauge doesn't seem to work. The cluster she wants to use has only 2 gauges fuel and temp ,with Idiot lights for oil press. and alt. I'm wandering if this swap will work without problems !?Any suggestions would be appreciated ! Thanks, ...cougar...
