It has driven me crazy for years to have a temperature gauge that I can't really trust and an oil pressure gauge that is an idiot light in gauge form.
I found a product called MeterMatch from a company called TechnoVersions, and worked with them to make it work well for our Mustang clusters. I put two units into my cluster wiring harness, one for the temperature gauge and one for the oil pressure gauge.
You can read the write-up on how to do this mod here.
Here is a picture of both MeterMatch units on the harness:
