Noise From Under Dash while driving
 

Hey Everyone -

I have a 67 Grand Prix that I have been doing some work on and just recently the car started making a strange noise that appears to be coming from under the dash near the steering column as best i can figure. :(

After I exceed ~25mph it begins by making a ticking noise that sounds something like taking 2 basic key rings and tapping them together very quickly. As I continue to accelerate it becomes more of a squeeking/rattling. It will come and go at irregular intervals (1 minute of noise, 30 seconds without, 30 seconds of noise 2 minutes without) and I have not found a way to cause it to occur or make it stop. There hasn't really been any change in the driveability of the vehicle, just an obnoxious noise!

I can't really capture the low mph 'ticking' noise due to background noise, but I was able to get a video that somewhat captures the louder squeeking noise in the link below! :confused:

Any thoughts on the culprit will be most appreciated!!!
