LOOKING AT LIDS FOR BTV
I spent part of the morning disconnecting the vaccum lines and plugging them on my Easamatic system. It's easiest, I think, to just disconnect the line at the intake manifold fitting, plug it, and cover the end of the fitting with a piece of hose with a bolt in the end. (Time-honored tradition remembered well from disabling various vacuum lines on the old "smogger" cars of the 80's)
ANYwhoo, I also checked around to see what kind of MC Reservoir Cover I had. I really can't tell without pics of each style "original flat" or "new style." The cover has some raised portions between the screws, but all in all looks pretty flat. I'd take a pic but, as you know, the steering shaft all but obliterates the view of the cover, so everything I've done is mostly through "feel."
If I knew for sure if I had the oldstyle "inside" vent as opposed to the external vent, I could have my rebuilder double-check this to make sure the gasket clears.
Sorry to be a pain with the questions, but I just want it done right the first time. Maybe I'm wringing my hands a bit too much, but it might just improve the odds.
BTW, driving with vaccum lines disconnected is very tricky. You often have t pump the brakes, even to get a reluctant stop. (I'm sure there is some air in my lines as well, complicating this.) And you need to be ready to use the emergency brake at all times, especially when coming to a full stop. (Having a manual transmission helps a lot. I only did this to be able to get the car to the shop several blocks away, where they will perform the Easadectomy this week.
Hope someone can post clear pictures of each of the two different covers. I really appreciate it.
HH56's original gasket photo: REALLY HELPFUL. I just need detailed lid shots.

The first units when introduced in 52 had a lower port opening just under the lid and in the reservoir. I don't know when the change was made to the next version. You will have to look at yours to verify but most likely it is the one in question and needs to be checked.
Here is a compilation of photos posted over the last 2-3 years detailing the issue. Some photos mine, others by KevinAZ. Top row shows items for the flat lid. No gasket over the port because there was no need with the lower opening.
Lower photos show the different gasket used with the port change. Probably supplied by Bendix & has been found many times on supposedly never touched factory original units -- and the port was blocked by the lid. The other photos show port all the way to the top and one version lid out of several available. Other mfgs used different lids to accommodate the raised port design. Packards original style flat lid totally blocked the port opening.
