Dash Cluster Question - 68 Barracuda

Couple of questions:

With the LEDs and the Rallye dash, did you remove the original mounted blue bulb filters?

As far as color, green seems to be the consensus, I was thinking blue. Does anyone have a preference?
I went with blue LEDs looks cool my dash is a house of colors green. It's what you like is what you go with.But I would definitely do what dragtop said if the dash is out put power to it ,I'll bet you'll have to fix a couple grounds
