I have a combo temp gauge from a 1973 914 and taco plate assembly with sender, cover and wire harness with brackets. Wire should probably be replaced but it gives you the correct brackets for properly running the wire to the top of the engine.
The gauge has some rust on the inner bezel.

Asking $75 for both the gauge and taco plate set.
Prefer to sell them together ofr $150. Flat rate Priority shipping for $11.35.
