Aftermarket Gauges in a Stock Magnum/Cordoba Dash Panel

About 15 years ago I ditched the stock dash in my Magnum for a custom dash panel and Dakota digital gauges.

What was Kool then is not not so kool now. I want to go back to a stock dash, but fill them with aftermaket gauges.

Problem is that the holes are 2 4" and 2 2 5/8"

I can find 4" Speedo and Tach, but the selection sucks. Then I only have 2 holes but need Volt, Fuel, Coolant temp and oil pressure. I guess I can put the gas and oil pressure in the dash and get a pillar pod for the Volt and temp. However, I'd prefer finding combo gauges if possible.

Has anyone ever put aftermarket gauges in a stock panel? What did you use and what problems did you have?
