Mine is a 2004 XLT, extended cab, 4x2, 4.0L SOHC, AT with 231k+ miles.
A few years ago I had the 60/40 seat reupholstered in leather and the rest of the interior is in excellent shape. I have kept the maintenance up on it and replaced the cheesy Ford AM/FM cassette radio with an Alpine unit and upgraded all the speakers with Kenwoods.

The idea I have been kicking around but have not brought to fruition is to replace the stock instrument cluster with a Dakota Digital one. The problem is, they do not currently have an instrument cluster designed for the Ranger so it would have to be a new custom design, which they are willing to do for a price. Four years ago they quoted nearly $2500 to do one.
Dakota Digital does make one for the Mustang and the instrument clusters look very much alike. However, I have to wonder if the circuitry and other components within the system are shared across the two platforms? I am far from an expert, especially on anything Ford or newer than 1978.... However, back in the day when I was bending wrenches for a living, it was common for manufacturers to share as many components across their divisions and models as possible. A windshield for a Camaro was the same one as the Firebird, etc.

Does anyone know if the Mustang and Ranger instrument clusters are interchangeable?

 

Probably not, also 2004 and up Rangers the instrument cluster is part of the PATS.

 

I think they’d look good on my build.
