Gauges?

[noclrnce]

I went through the search and didn't really get what I felt was a "solid" answer. I have an 83 k10. The only factory gauge that works is the fuel. A couple of the other gauges have some cheap aftermarket ones swapped out by previous owner. The temp one works the others don't. My truck is a manual so I thought Id look for a tach cluster and just replace it all and be done with it. From what I read 78 and up is what I will need? Some threads claim they are plug and play, some claim I have to re pin connectors. I dont have cruise control so that really wont bother me. What exactly will I need to do here?
