From a '78 98, aka a vacuum gauge.
Good overall condition, working,
The first picture shows the gauge with some vacuum applied,
There is some discoloration of the colored bands in the face.
I have the dash bezel, it is in poor shape but has the window for the gauge.

$20 plus shipping.

 

That is cool! I'd want it if I had one of those cars. Never saw one before...

 

Last call for the gauge, the bezel is gone - got thrown out accidentally.

 

Very cool part. I've seen those on earlier 98s as well. GLWS!
