Dumb question about gauges

[Risejugger]

Hello

This is probably a dumb question but better safe than sorry

I am restoring a 1977 Thundercraft Magnum 160 SS. I am replacing all the wiring and rebuilding the dash panel (Old one rotted away). It originally had a speedometer and a charge meter and that was it. I would like to add a tilt gauge, tachometer, and fuel gauge.

My plan is to not replace the decorative cardboard and plastic panel that the old gauges and helm were mounted through and simply cover the dash with vinyl drill the holes for the gauges and steering wheel and mount them.

My question is...are there any safety issues I should take into consideration? For instance do the gauges get hot enough to be a fire hazard? Since they are not grounded to the chassis like an automobile, I don't see any electrical issues?

No the gauges will not get hot enough to melt or catch fire to anything. The inert dash material doesn't carry a bond, so you'll have to provide a ground bus, but this is typical of these types of installations.
