I just scored a few Barracuda dashes to piece together to make one good one. One has a factory tach and the other two have a performance indicator. I was just wandering which one was more desirable?? I'm not sure on either. I would like to use the tach, but not sure if it works. Could I just hook it up from the coil like a aftermarket tach???? I haven't cracked none of the dashes open yet to check any of the guages but they are super clean and all look like they should work. And on the performance indicator, is that just a vacuum guage?? or how does it get hooked up or tested to see if it is working. I'm wanting to fill the empty hole in my dash with something just don't know which one to use
