If you have a local pull a part type place, obtain a 2nd cluster housing with circuit board and the cluster plug. Depending on the place, you can save money by leaving behind un-needed guages. Now you can modify the 2nd cluster with the layout you want. Some Dremel work may be required. Note the year the 2nd cluster is from, and obtain the matching cluster plug pinout. While the plugs are the same for the years of the squares, the pin layout changes. When you are ready for the swap, you can repin your existing truck's plug. You can use pins from the 2nd plug to fill in blanks if needed or to replace pins damaged during the move.

Before the installation, use the 2nd plug to test your connections.

In process of doing this for my 75 using a cluster from an 87 Suburban. Went with the LMC tach in place of the existing gas guage and separate small gas gauge. Adding LED back lights in the process. And a factory voltmeter instead of the dead Amp gauge. At my pull-a-part, gauges are $5 each for the little ones.
