Carl my dealership was open today for a very limited operation, I wasn't in but got my boss to check for the switch and our AC Delco supplier, but no luck.
Thanks for checking. I've pretty much exhausted GM as a source, yes.

There is an auto wrecker near me. I could see if he has one if you like.

Thanks, I think I found a place that will be open on Friday when I get out of jail and they have at least 3 cars that will have the right one. I may have to go for a ride on Friday, it's about an hour away.

I was just looking at a couple pick n pulls including our local one but noticed the one in Calgary on Barlow Trail just got in a 98 Park Avenue this week. Another option. I finish my term Friday.
Bad news is, the switch doesn't do what I thought it would do. Good news is, I didn't spend 50 bucks getting one because that's what it would have cost by the time I paid shipping etc. I ran to Winnipeg to day and went to Buck's Auto. What a miserable day, cold, windy, snow squalls to deal with but it only took 5 minutes to get it out and the girl at the counter says "You can just take it" when I went to pay! I put a fiver on the counter, thanked her heartily and told her to at least buy some donuts!
More details on the switch later when I have more time. I guess I'm still looking for a switch that will turn on the brake lights and dump the vacuum for the cruise when I step on the brake pedal.

My 66. I'm putting an aftermarket cruise kit in it, concealing it as much as I can. The servo is hidden inside the driver's side fender. I'll hide the switch down at the bottom of the dash somewhere so it's not very obvious.

Carl, would an egr solenoid valve work? You could wire a Bosch style relay to your brake light switch to control the solenoid. The only thing that I am not sure about is if the vacuum would drop fast enough to release the cruise control.
I will have to look into that, thanks for the idea. I had thought of using the switch to control a relay but couldn't think of a 12 volt vacuum switch. I thought of the one for the lockup converter but that's backwards, the vacuum controls the switch, not the other way around!

If you look in the area of the back brace from the fender to the inner fender you might catch a hint of the servo in behind it. You can see the vacuum lines and the wire harness running from there towards the firewall. Nice thing was, no new hole in the firewall because when I converted the speedometer cable opening in the firewall to the correct place for a 4 speed car it left a hole exactly the right size in a perfect spot for that stuff to run inside the car.
Whats used on more modern clutch pedals to cut off cruise? Could you look there and use the same setup for the brake pedal? My vws and Tacoma have this shutoff.

Man, I've looked high and low online at all makes and models. I can't find what I need. It needs to be a switch with 2 pairs of terminals plus a vacuum valve. When the vehicle is at rest, the one pair of terminals is an open circuit (brake lights), the other pair is a closed circuit (cruise control). Both circuits reverse their position when the pedal is applied, plus the vacuum valve dumps the vacuum when the pedal is applied.
I called one of our technicians from work today. He's at home until this whole mess repairs itself. I asked him about an EGR solenoid and he thinks that will work but he said the fuel tank purge solenoid on the newer vehicles is even more compact and from what he remembers it will work the way I want. I'll have to get one of those and test it. I can power that from a relay that would work off the brake pedal switch. I already have the clutch switch done, that was easy. A brake switch from an automatic vehicle with cruise and lock up converter has exactly what I needed (pedal in normal position, vacuum holds and circuit is complete, pedal depressed, vacuum dumps, circuit is open)

So I take apart the D2296A from the wrecking yard to see why the vacuum port doesn't hold vacuum.
Why would they make it this way? It has a vacuum port but was never intended for a vacuum switch The other side of the vacuum port does nothing. It just has a little hole in to the atmosphere.
