Hey guys, I'm looking to make my dash gauges more useful. The rectangular 64 Speedo/dash I have doesn't leave much room for other gauges. Which gets me to my question.

Is the 1964 GTO's metal dashboard faceplate the same size as the Oldsmobiles? There are a few aftermarket options for them which would save me quite a bit of time. They look close, but I am not sure.

I don't want to cut up my stock dash much so I'm either going to be buying another Olds one and fabbing something myself from it or finding something else that fits.

It is hard to tell on sizing/measurements, but it looks similar to the eye.
