The project is not impossible, but it is fiddly. By that, I mean that getting the dash apart and the cluster out is as easy as it gets. But then one has to remove the circuit board and the gages' needles to get it apart to the level one needs in order to put in the modded lights and instrument card. It is not impossible, but you have to wrk so, so carefully to get the needles back in the proper orientation so they are not off terribly. Rlith & Blazee might come along to help some more. All I have ever done on these gague panels was swapping the gages as an assembly for a friend and having him enlist the aid of a local dealer to set the proper mileage on the Odometer for him. I've never broken one open to swap the cards out, though it really gives the truck that posh, custom look if done right. Put in some current limited LEDs (Blue) to give it that eerie Indiglow look on some of the imports and Dodge instrument clusters.
