1974 duster dash cluster problem

Hi,I just finished a int. project on my 1974 duster. I took the cluster out for a while and then I put it back in. The SAME way i took it out. for sure! I labled everything. I put it back in and the only thing that works is the amp meter and speedometer . I know the amp gauge works because it has power to it. and the speedo is mech. everything else has the circuit board. is it possible for these to go bad? where can I get a new one? is the whole cluster junk? Thanks in advance for all help. :burnout::D
