Swapping out non working speedo/adding a radio

When you get to the point where you have to unplug your dash board to get it out be very carful unplugging it. If you break off the pins on the board you are screwed. I took a very thin screw driver and very slowly pried up on the plug one end to the other. Mine did come off with no problem just be careful. I do have a spare dash if needed. You can pull just the speedo out to replace it. My speedo wouldn't go past 60, the needle would stop right at 60, what I found was there is a black tin plate in front of the entire gage cluster and that was hitting the needle preventing it from going and farther than 60 mph. I shimmed it out a little with nylon washers and she now works perfect. Just go slow taking the plugs off and be carful not to break the plastic lock on your speedo cable when you go to take that off. I ended up pulling my bucket seat right out of the car to give me more room to work under the dash to get to the speedo cable.
