Ok, So getting really close to getting the car up and going for this year.... I have a three year resto plan but in the mean time I can still drive and enjoy car.
I am planning on eventually doing Hood tach (when I do repaint) and adding the rally cluster gauges so I have a factory look with the temp, volts, pressure,

Before I do that I think I want to add inexpensive gauges so I can still monitor all this... I want something that more subtle and does not permanently attach etc... cause I plan on keeping a pretty original look in the long run.

Any recommendations??

I'm thinking for the tach just a small gauge with column clamp of some sort...
