Default Cruise control diaphram ?

The vacuum/diaphragm part for the cc apparently is not available in the vette catalogs.


What is the solution to replace a defective one?


Thanks

I see used ones all the time on flea bay. I would check there. Do a search for a cruise control "servo".

The one on a 84 corvette looks similar. I'm not sure if it would fit though.
Another option is to use the 78-82 ones that mount on the intake manifold. I've been looking years for a spare one for my 77 but have never seen one for sale.

Not a single c3 servo on Ebay. Where are you seeing these 'all the time?'

Can anyone verify that the 84 would work? Looks like it might

Man I feel bad now.

So I'm chasing down a lead on one on the local craigslist. In the meantime you can contact txvettes on eBay and see if he has any. He doesn't post everything that he has in his yard. I think his store is called Uptmoore's Corvette Parts. I'll let you know about the one that I saw on cl.

The problem I see with trying to find a 40 year old servo is that the rubber part will be rotted out just like mine is. And I would imagine that a NOS would be a fortune.


The big question is where are all the people with deteriorated servos? I can't be the only one. Someone must have come up with a reasonable solution by now.

Yup--I completely removed the CC option (all components) on my '77...,most reasonable solution I could come up with....
