Filter Bypass Valve
I heard rumor that it will be hosted by the home club of the ZCCA Treasurer. Here's the way to find out at ZCON before they announce it. Look around at registration and ask people working there who are not ZCCA officers (and family thereof) if they are with the host club. Most likely someone will respond, "No, I'm with the such-and-such club." Those people are at the convention to learn how to run registration for the next convention. Of course, there's usually plenty of loose lips around the convention saying where the next one will be held. The last few years only one club puts in a bid. For those of you who are not members of your local Z club, please join, especially if it's a ZCCA club. If it's not a ZCCA club, join and try to get them to join the ZCCA. It's only through the support of local clubs and the ZCCA that it's possible to have the conventions. If you haven't gone to a convention, consider going. Even an introvert like myself can find things to enjoy at the conventions. (Actually while many people are trying their hands at pub-crawls, I'm usually looking at the cars/photographing the cars/talking to the car owners.)

Lash Pad 240z
Human sacrifice, dogs and cats living together... mass hysteria! Seriously, the wrong lash pads will mess up your camshaft. As you see from the group feedback, the smaller lash pad isn't making much sense.

Plug wiring for distributor 1974 260z
Quite possible, CO. It may affect the range of adjustment of the distributor. Of course, I may find out if I choose to go with that distributor in the future. I would use an HEI with it in the 73.

Plug wiring for distributor 1974 260z
The three wire distributor is for a dual pickup...for an automatic transmission 260Z. In theory, the OP could cut the plug off his wiring harness and off the new distributor to wire them correctly. I wasn't sure if he wanted to cut connectors off. Finding the common wire isn't difficult. Finding the wire that goes to the correct pickup is more of a challenge. There is no place to put a meter probe to find out, so you have to trace the wire by hand. Here's a photo of a dual pickup distributor. I did some examination of this distributor and it looks like the female terminal by my thumb is for the pickup closest to the vacuum advance.

Plug wiring for distributor 1974 260z
FYI: Here is a listing for a manual transmission distributor. It says "Not in Stock". I don't know if that means they can or cannot get it. Some of us tried to order windshields through Summit a couple of years ago, and that turned out to be vaporware. https://www.summitracing.com/parts/aaz-31-615/make/nissan/model/260z/year/1974

Plug wiring for distributor 1974 260z
The 3-wire plug is for an automatic. The bullet size is different from pretty much all of the other bullets I have in my collection, too.

Z's on BAT and other places collection
https://www.ebay.com/itm/324721775605?hash=item4b9aed13f5%3Ag%3APRUAAOSw1-Jg9zYr&LH_ItemCondition=3000|1000|2500 The seller is probably looking to take advantage of the hype. Supposedly only 15K miles. Car has been sitting for 34 years, and has the "California rust" on the hatch sill. It might be a good restoration candidate.

Best Penetrating Oil?
One tip I have used for breaking loose bolts: Before you try to loosen it, torque it slightly tighter. This may give you a little wiggle room to get it started turning the correct direction to loosen it. This actually worked for one screw when I was trying to remove the grille. Don't forget that heat can be your friend. Sometimes a heat gun is enough.

Ignition help needed on '78 280z
If you have a similar issue, you may just want to create a new thread.

Best Penetrating Oil?
Kroil is one of the best commercially available penetrating oils. You can get it as a spray or liquid in a can.

Vin look up?
It's doubtful. You'd have to find people at the DMV willing to research the title, and if it changed states, that means working with another DMV (or several) to research the title. That's providing they would even do such a task.

Blown Brake Light Fuse
I did this drawing several years ago to address some of the confusion on the turn signal/hazard light/brake light circuit. While it is specific for the 72, the 70 should be pretty close. Some of the connectors may be different. https://fiddlingwithzcars.wordpress.com/2013/01/20/hazard-switch-brake-light-turn-signal-circuit-analysis/

Farewell Sale - Early 1974 Datsun 260Z Parts
Um, he didn't say he was the first owner, so what he said was correct from an English grammar standpoint. He was saying he owned it 43 years. Was there a point to your reply?

Drier recommendations
I looked in the AC section of the 74 FSM. It says that the switch is a high pressure switch. I wouldn't be surprised if Amazon doesn't have a high pressure switch (or high/low pressure switch) somewhere that has the same threads as the switch Jim used.

SS Bumpers from Vietnam
It's good you didn't go with the rubber strips. Today I was tightening/replacing hardware on the rubber strips. I'm glad I have the portacool in the garage when I want to work on the car this time of year.

Coil Question
If it's not the coil, consider going from the Crane to the Pertronix. It's stupid simple to install the Pertronix.
-
Coil Question
I would not use a 0.4 ohm coil unless you are keeping the ballast resistor. I wouldn't go below 1 ohm unless you are keeping the ballast resistor. I was suggesting the 3 ohm down to 1 ohm since it sounded like @7tooZwas planning on jumpering out the resistor. Using a 0.6 ohm coil with no resistor would mean about 20A current through a 14 gauge wire.
-
Coil Question
You might see better performance with the 1.5, but the 3 should work. The spark may be a little weaker.
-
Coil Question
I was worried about the tach performance with a 1 ohm coil. This morning I installed a Pertronix with a 1 ohm coil into a car and bypassed the ballast. The tachometer appeared to be functioning correctly. @7tooZ - You could go with a Pertronix 1.5 ohm coil (40011 or 40111) or MSD 82023 coil. It looks like you can bypass the ballast resistor with no ill effects, too.

Pertronix Flamethrower 3.0 Ohm coil...You can get it in oil-filled or epoxy.

Coil Question
Are you still using the ballast resistor?

280z master fuse list?
I didn't say there was a list. I said it is all laid out. The list I gave was from looking at the page in the BE section for the voltmeter and going back to the wiring diagram to identify all of the branch circuits. The power for the hazard lights does not come off the same fuse as the voltmeter unless someone changed how your car is wired.

Coil Question
Many coils are oil filled for the heat dissipation media. You may see residue around the center post of the coil. Some auto manufacturers did vertical mounting of the coil to reduce the chance of losing the oil. However, the oil will break down as it ages, providing less heat removal.
