I have a 1978 silver anniversary that I am restoring. I have decided to begin with the interior since the exterior is in great shape and the running gear is new. I am currently removing all the parts and replacing them. I am to the point where I need to remove the dash and would like some input on the best way to do that. I have begun to remove the speedo and tach compartment but want to be careful as to not disturb the wiring and cables. The enter gauge cluster seems to have the same issue. Can someone direct me to or provide me with some kind of easy to decipher manual or diagram that would aid in this procedure? Also I want to replace the speedo and tach with new ones but find it difficult in which to locate any. Any ideas???
