I have a Buick vacuum gauge for ?????? what year. It mounts in the chrome cup like the tachs. the scale runs from 0 to 24 in manifold vacuum. I can't find anything in my 64 parts guide for it. The back of the gauge has JAN 16 and 56533574 stamped on the back. Can anyone give me an idea what year it is from? Thanks Larry
Hi Larry I don't recall Buick ever having such a gage. I know that the early 1962-63 Olds had a vac. gage. that mounted on the console. some sat into the console and othere had a teardrop cup. Jim Schilf palbuick
The chrome cup is the same part number as my tach cup. It also has the same adj red line knob. I did wonder if someone put a vacuum ggue in a tach cup. I thought about taking a 7K Pontiac tach and putting it in my cup instead of the 6K one in there now. Larry
