I'm trying to install my new gauge faces, but I can't get the cluster out. I've got everything out and I'm at the point where I need to get the speedo cable off and disconnect the electrical connections to the cluster. I need to know far I can pull on the cluster. I'm afraid to break something if I pull too hard. How much hard can I pull? My Haynes book says to disconnect the cable from the transmission. I've been at this for 2 hours and it's driving my NUTS!
