More on '94 Oil Pressure Temperature Meter Gauge

[Espritman]

Here's what I find when searching for even the later version of the gauges:

15 78150-SL0-013 METER ASSY., TEMPERATURE & OILPRESSURE 1 - Discontinued Part

Is there any direction about where I might locate an earlier or later NOS or repair the one with the broken needle?
