speedometer

Is there a fix for when the tach and speedometer needles start to bend. The ones in my '79 were not bent but the car spent some time in a hot environment and the result is the needles are starting to bend. Has anyone 3D printed new needles? Or is the only real alternative to swap in a new to...

I'm looking for a 15 inch speedometer cable with both ends threaded. This is the one that connects to the odometer counting unit in the front trunk. Or if you only have the inner cable that would work too. Any help appreciated, thanks!
