I guess I'll be the first to respond here too...
You can get autometer speedometers in both mechanical and electronic. If you are replacing the original, a mechanical will work fine with your original cable. They also have there own lights that you will have to supply power to.
Just so you know, they are not a direct fit, but they are fairly easily adapted. I'll attach some links to help you out.
..turn signals you have to be a bit creative. In the link they mounted small led indicator lights. If you go through several off the old posts about autometer gauges, you can see some of the cool things other guys have done.
