Does anyone know the name of the supplier of the speedometer cable driven cruise control servo (see pics) that chrysler used on all their vehicles I am attempting to contact them if they are still a viable resource for the rubber vacumm diaphram that fails with age an causes the servo to stop working. It was even available through the sears catalog in the 70's as an add on kit for any car I know because I purchased one in 1976 from them.
