Zed Head

If the light is right you can probably see the notches through the hole. In practice you just jam a small screwdriver in the hole until you feel it grabbing the notches of the adjusting wheel, Keep jabbing to get the wheel to move. It's kind of tedious, you don't get much movement per unit of effort.

There's a hole in the brake drum. Had a rubber plug in it. Might still be there.

Z's don't. No guarantee that the drums will come off even if you back the adjusting wheel off. People have had to sacrifice the drums if they're really stuck. But, the best place to start is the instructions in the FSM. Back off the wheel, see what happens.

Actually...

Were you shipping as a company/corporation or as a private individual? I had wondered if S30.world's paperwork problems were actually tariff problems. I wonder if the guy buying the E30 head had driven across the border to purchase it, would he have had to pay the tariffs? Or how much trouble would he get in to if he didn't declare any purchases. Or called it a personal item. In a way, it is. https://www.cbp.gov/travel/us-citizens/canada-mexico-travel#:~:text=All%20articles%20acquired%20in%20Canada,TTB)%20regarding%20individual%20state%20requirements.

It doesn't really matter which terminal has the condenser attached. It's there to stop electrical noise.

Just leave the condenser disconnected. You don't need it for now. You can also just connect both of the wires from the ballast resistor (the block) to the coil positive. You don't need it when you use the HEI module.

I would add some details of how, exactly, you are evaluating "spark". With a spark plug at the end of a plug wire, through the coil center terminal, with a spark tester...? Are you cranking the engine when you do this? Have you disconnected the original module by the fuse box or did you resintall it? And, or, but, I have noticed that you do not have any battery power going to the coil in your picture. You only have the coil connected to the module and no pwer to the module either. You need power to the coil positive terminal. Also, use your meter and make sure that the mounting screw of the module has a good ground. And make sure that it's the correct screw. Only one of the screws completes the ground through the module, it has a thicker ferrule. Looks like you have the correct screw but you might not have good contact through that screw head or where it seats on the TB. The TB is not the best place to mount it. That's where all of the coil current flows when the module is doing its thing. And, it you plan to run it for long you need a proper heat sink under the flat part of the module. It gets hot and heat will cause them to fail.

Here's a good one. Couldn't wait for Saturday. https://youtu.be/dQw4w9WgXcQ?si=grkFLcz2wcNdPoJP

The VR Z did not reach its reserve. Didn't get to its last sale price either. https://bringatrailer.com/listing/1972-datsun-240z-380/

Thanks for replying. From out here, the post reader, the sigh sure does look like a comment. Just couldn't tell what the comment was about.

The original struts used special oil. Aftermarket strut insert replacements don't need any oil. Not sure what you're working on. p.s. if you click Signature, put stuff in the box, and save it, it will show up at the bottom of your posts. https://www.classiczcars.com/settings/

I suppose it depends on what the worry would be. Worry about them failing? Spring sag with age is not uncommon. Did you notice any variance in corner height when they were installed? The thing about aftermarket springs is you don't really know how they'll sit until you get them installed. You can find reports of weirdness with the Eibach progressive rate springs. Don't know if that problem ever got solved. It's a conundrum.

Seems to be normal and as Nissan intended. Maybe to offset an imbalance in the car's weight, maybe from the engine tilt. Not clear, although it might be described somewhere. I don't think that the aftermarket considered it.

It's just snark if you don't follow it with something useful. Are you sighing the pan question or the build details?
