Cluster with factory tachometer

[4x4 in Kansas]

I would like to replace my cluster with gauges with a cluster that has the factory tach and gauges. I need to know what years will fit and work correctly without having to cut and splice wires. My truck is a 1983 K30. Thanks for the help.

I believe 1978-1989 are plug and play. You will have to run the tach wiring but it's easy.
