Dad is converting his to hideaways, and keeping the factory vacuum setup. The electric stuff is pretty darn expensive.

Our RS 69 Z has all of it's born with vacuum headlight parts, including actuators, vacuum lines etc... and this system works very much the same as the GTO. The headlights still work fine on this one and it's 50 years old and used on a daily basis. The dust boots on the actuators are dried out and falling off, but it still works, lol. So I have pretty good faith in the factory vacuum systems and they are pretty easy to diagnose if there is ever an issue, very simple setup.

Hey Y'all
So I am getting into these Hideaway Headlamps there are all kinds of screwed up things going on But most importantly (because its what I don't know) is about the spring & the Actuators
the headlamp doors don't go up & they stay down.

I borrowed a smoke pot from a friend . Until I can buy my own.

Hooked up the smoke pot to the main coming off the carb ,worked the headlamp switch ,checked the canister & the actuators , & nothing. then with the grills removed I put the smoker on the top of the actuators & both leak out the shafts.

I also rigged up myself a super sucker from my A/C vacuum pump thru a old R~12 Manifold so I can test/ suck things like bleeding brakes & what not.

I was test / sucking the actuator on Pass side & it sucked up old dirty rusty crunchy water out of it.

So I am thinking they are done

Will someone please direct me to the thread or article on how to deal with these my searching has not been fruitful.

Any & all help is greatly appreciated.

SO upon further removal & inspection does this work with the boot on the shaft making a seal? if I plug off both vac ports I can not move the shaft up or down.
It would seam to me that the diagram is intact.

what seals it to the shaft?
