1969 Dodge Dart GT Dash Cluster

Hello,
I am looking for the cluster for my 69 Dart. The speedometer has destroyed itself and we're (the mechanic and I) not having any luck finding someone who might be able to fix it. He found someone in Tampa that does this exact thing but because its analog he doesn't have any parts for it. If anyone knows a business that can fix it that would be great. Or even a speedometer that can replace mine in the cluster. Any help or ideas would be greatly appreciated. Thanks
