Stereo Installation Help
 

What is the best for cutting the dash to install C D player?I didn,t want to go this route but my son shows up with his buddy and wired the system together but did not want to cut up dash and left me with the task

Probably a jig saw with a proper blade, or a good cutting disc, barring that you can use a drill, then file/grind the hole smooth

If you have either of these air tools, you could use them for a fast, easy, and very clean cut:

If you do not have access to these tools, then I would recommend using something like this:

You may also want to use a drill to get some starter holes on the vertical cuts. Or you could cut both top and bottom, then bend the side inward (not as clean, but works and not visible after installation).

Whatever cutting tool you choose to use make sure the blade is for cutting thin steel. Using the wrong blade could make it harder to cut and the cut would not be as clean, possibly nasty.

I would recommend the airsaw, it's a much cleaner cut

A dremel tool with a cut off wheel works great. Small and fast to use.

Thanks again,great tips.

A Rotozip with a metal cutting bit in it is a great tool for this.

We wanted to install a temperature gauge in the 80 suburban as the stock one was removed and replaced with a tachometer years before. (it was an ambulance, only had 2 000 kilometers on it, was stored indoors and was maintained very well. It ran perfectly and was in complete mint condition, at least until we sold it to my uncle, my truck is in better shape now, a terrible waste of a truck...) Since we still wanted the tachometer, we just used a soldering iron to melt through the plastic dash and install the new temperature gauge, it looked totally factory installed and very clean. We needed the temperature gauge as we used it as a hauling vehicle, and it overheated on us once...
