Your gauges are they standard round Stewart Warner diameter?
Or some other size?
Either way should not be hard to find a vintage VM gauge or a retro looking replacement.
A couple years back when I was rebuilding my Land Cruiser panel I had a catalog with a nice looking (vintage chevy style) VM gauge that had a small blue (dim-able) barely noticeable digital amp reading in the bottom center. Best of both worlds, today's digital world meets vintage iron.
