Great how-to Wagonman. A couple items to add to this. Many Corvette aftermarket suppliers sell the number sets for '57 Corvettes that I would think are interchangeable with the tri-5 sets. Also, the internal gears are not available. I'm sure someone makes them, but they are not available to the public. I tried several speedometer repair and parts places to get one for our 57 Corvette, but all they will do is rebuild your unit. If you are lucky, you might be able to file down any bad spots on the gears to get them to run smoothly. It worked for me.

Thanks!! this we will help me a lot!! My speedometer is out of a 56, they looked the same from looking at the 57 pdf. My speedometer cable broke and I some plastics peices remains are still inside, I've read a thread to use a drill bit to remove the plastic pieces, drilled and removed some pieces, but when I stick a needle in it, I hit plastic still, I assume if im hitting plastic with a needle there are still remains of plastic pieces in the gear? Is it solid at the other end where the magnetic spins with the cable? What is the best way to remove the plastic pieces that broke inside? Thanks!

From my experience many of the internal parts will interchange up into somewhere in the 70's so that would open up the possibility of parts availability. You only have to match old parts against replacement parts to make sure. Some parts also depend on the sweep arc of the needle to be compatible.

I haven't personally done it but have seen a speedometer head in a 57 that the owner exchanged the guts from a later model with the trip function and with a bit of work on the face and lens had a nice looking speedometer with a working trip odometer.

If you are talking about the square hole on the back of the speedometer head, the hole is about 3/4" to 7/8" deep. You will have to drill it out with a small enough bit to about that depth and with a large pin or needle, try to dig out the remaining bits. Going to be very tedious work.

Are you talking about having plastic parts in the speedo cable housing? If the cable is broken, take it completely out, and use compressed air to blow out the housing. Then you can put in a cable repair kit and use liquid graphite (speedo cable lube)when you have the new cable in the housing. Then work the cable back and forth (top to bottom) to insure it's lubed all the way down.

The plastic end of the cable that connects into the square hole has completely broken and I've gotten some out. I'll continue to drill and dig with a pin and yes its tedious work. Thanks!!
