Yes it does. With the same screw also. It's also attached to the dizzy body the same way as well.

There is only one difference, minor one. The vac inlet port is on top now where the 280 inlet is on the bottom side of the can. Get some extra vac line just in case. I didn't need any but.....

I did still have a vac can for a 77 280 that is defective. Going to die sect it some day. I installed it in the 80 dizzy with no problem. Same goes with the new one, 81 maxima, and it fit.

I going to see if I kept my old vacuum can from my 77 distributor and see if it fits in the 80 unit.

Zed Head, are you talking actual size of the "can" or function?

I could have swore that I tried a regular z vac pot on the zx one when I started having a problem with mine. And it fit.

Not sure, waiting for Zed Head to reply on the differences

It'll have the ignition module on the side facing forward on the distributor cap. Sometimes known as the match box.

All I did was highlight the page, copy, and paste.

No to all of your questions. Bolted in like the original. I was willing to take that chance when I ordered one. Mine was bad as well. I don't recall if there is a difference between the 77 and 80 advance plates so keep that in mind. I've been running an 80 distributor for 3-4 years now.

I put one of these on my 77 that has an 80zx distributor and it seems to work just fine. Rockauto.com Not sure what year Z you have.

Was checking them for a friend and discovered they are sold out.

Okay, makes sense. Thanks. As you can tell I usually stay away from "electrical"..... Afraid of it.

Good to know. I've heard it could over heat the old wiring. Not true I guess?

Isn't that dangerous on the old wiring in our Z's? Just curious.

Maybe MSA will send you the installation instructions.

Exact reason why I'm replacing mine.

I love the su's. Ran them on my 280 when I was in Nevada. Never had any issue with them.

I can just make out a raw fuel smell when coasting now. I didn't have this before. That extra air entering the intake is no longer there while coasting. I would have that with a working bcdd.

Yes CO that is what they do, measure while on the dyno. They spin the drive wheels at 15 mph and at 25 mph in the smog test. And I have a complete understanding of its, the bcdd, operations. Or at least I claim to. I appreciate your expertise for sure.

Looks like I have one coming, already! I thought it was going to be harder to find. Our good friend Wayne (wal280z) is shipping one out to me for just postage! Will post results and may even, time permitted, open up the entire non working bcdd to see what I can find. And just for fun. There is another thread on it but I want to open mine up to compare.

This will increase Hydro Carbons and you could possibly fail emissions. The block off plate does the same thing with one other mod. Really simple. But I did this so I could still drive it. If I were testing emissions right now I would fail visual or HC's or quite possibly both.

Yes long ago you could just remove the bcdd but due to age the gasket is extremely brittle and almost disintegrates when separating the two. I have tried on 2 others that's why my request.

Looking for a throttle body and bcdd complete. A working bcdd. Long story short. I developed a vacuum leak at the bcdd that caused a 2500 rpm idle. After many attempts to repair, what I thought was wrong, I ended up installing a block off plate. Can't leave it that way, won't pass emissions. It has to be either a 77 or 78. These have 2 vacuum ports on the throttle body where 75-76 has one vacuum port. One port is for advance timing and the other is for the egr system. Hopefully someone has one. Here's a couple pics

Ewww!
