I have a speedo and a gear reducer out of a 2 ton GMC truck. I was wondering if anyone knew where to get the rubber diaphram for the gear reducer. This is mounted to the back of the speedo drive and has a vaccum source to it. When you shift your 2 speed rear axle, it pulls a lever down with vaccum, changes the ratio to the speedo so the correct speed is showing. Any tips would be appreciated.
The diaphram is bad on the reducer, giving me a leak and does not show correct speed.
Thanks,
Brent | | |

They used to be Ohio Valley Speedometer Supply, and changed the name when they started rebuilding automotive computers, etc. They repair just about any small electro-mechanical device, plus rebuilding speedo heads, gas gages, etc. I don't have a current email or phone number, but a web search should come up with something.
