Pretty nice 72 with a ~100,000 mile rebuild engine. https://bringatrailer.com/listing/1972-datsun-240z-377/

What's the tach needle doing when it's missing? Those E12-80's are all old, or if they're not they're probably aftermarket. Maybe it's failing.

You have quite a bit of work ahead of you still. Before you put a battery in it and connect it up take a meter and check for resistance between the negative and positive posts. If you have a short there will be very little resistance. Get the wiring sorted out before even installing a battery. Also, just a seed for future thought, be very careful that you know which cable is positive and which is negative. Nissan used black for both. Not uncommon to fry electronics on these old EFI Z's with a backward hookup. Looking at this mess it looks like the PO was trying to solve a problem or was getting ready to part things out. .

Probably want to check all of the air intake ductwork up to the throttle blade for mouse habitation before using the starter to spin the engine. The air filter box opens with the wing nuts. The AFM hoses need to have the clamps loosened. The hoses can be pretty stuck, you might want a thin screwdrive or a pick to work between the rubber and metal to break them free. Probably need to remove the AFM if you want to get the hoses off completely. The wire clip on the connector can be difficult. Also, check those fuel hoses. Looks like a PO has already fixed one. And the hoses to the injectors. Once you crank up the fuel pressure you'll know more. Might as well get a gauge also to check pressure and pressure dropoff. It will tell you if the regulator is blown out or the injectors are leaking or the check valve in the pump is shot. All common issues after sitting. That pump is probably shot just based on its appearance. The engine looks about ready to go. You'll want to check power to the coil and verify that the original 1975 electronic ignition module is intact, by the fuse box. They fail often. Open up the distributor and see if the bushings are shot. See if the vacuum advance and mechanical advance mechanisms are free. If they're not, don't force them, they can be saved with careful lubrication and disassembly but if you force a rusty mechanism the plastic ball brearing frame will break. I'd check the distributor before starting the engine, even the normal forces can probably break a stuck distributor. Ignore the blue arrow. I was going to mention the ZX fan but already did.

I'd take a test light or meter and see if the wire to the small spade connection on the solenoid is getting power when you turn the key to Start. You might have a cylinder full of coolant. Who knows. If you're getting power to the solenoid but it doesn't do its thing then you might have a bad starter/starter solenoid. Hit it with a hammer.

Those cylinders look great. What brand of camera/borescope? Four pages is a lot to review. Might help to summarize where you're at in the process. Cylinders look like they're ready for fuel, air, and spark.

If you're going to have a muffler shop do it why not them look at it and use their database to find one. If you're going to do it yourself, then trying the no muffler twin stack should be easy. If the dimensions are correct. Looks like what you have is clamped on, not welded. So trying some things should be easy.

Bushings.

toolman on Hybridz says that they'll be at SEMA Las Vegas in two weeks. Thought he had an account on CZCC but there are several toolmans listed here. They show what looks like a scrapped/stripped 240Z on a road in the desert. Facing the wrong way if it's meant to be in the States. On a road with odd yellow and white center striping. Combined with that Youtube short above with the cringey rap music, the whole enterprise seems strange. If anybody trys to buy a part from them don't forget about the tariffs. 57% now, could be 155% soon. If anybody is really interested it might be worthwhile to browse other car forums. They have an odd assortment of models shown. Here's one - https://www.carbody.com/product/classic-car/ford-parts/bronco-19661977-parts/ HybridZA COMPLETE EARLY MODEL 240Z BODY may be available soonA Chinese Metal Fabrication Company is planning to unveil a Brand New complete Early Model 240Z body at the 2025 SEMA SHOW in Las Vegas on Nov 4-7. They are looking for Distributors in North America.

Weak chatbot? Where are the emojis?

How many/much replacement parts before it becomes not-a-Z? Is it weight or number or volume or area? https://en.wikipedia.org/wiki/Ship_of_Theseus And, how should the new thing be described? As a restored Z or a replica Z or just a Z, caveat emptor? Somebody needs to "Get A Quote". At least it's made of steel, apparently.

That is true, but it could have been converted from auto. I'm just throwing out bread crumbs. Something is drawing too much current. Find the thing.

Actually, Amazon added a W.

Put a meter from the fuse exit to ground in continuity/resistance mode and see when the circuit goes open. Wiggle that nest of wires around. If the fuse is blowing it must be because that wire to the switch and lights is shorting to ground. Could be at the switch ( a bad switch) or after it. Or crawl under the car and test the pins on the switch to see if they're shorting to ground when you put it in reverse. Check the wiring diagram to see if any of the things after the switch are shorting to gorund. You didn't say auto or manual.

I think it depends on the weatherstrip. I have a vague memory of metal clips in the Kia Sportage weatherstrip. No adhesive was needed. Really though, just put it on and if it's loose put some glue on it. Handling time 10 - 20 minutes, full cure 24 hours for the Windo-Weld (Amazon can't spell). Sometimes marketing converts a problem in to a supposed benefit. They don't actually say that "super fast" is a good thing. Work super fast and you shouldn't have any problems. Forgot to say, cure time probably depends on relative humidity. It's a moisture cure. I remember using a moisture cure construction adhesive on a hot dry day in summer and it took forever to set up. Full Cure Time 24 hr Handling Time 10 min - 20 min https://www.3m.com/3M/en_US/p/d/v000074326/

p.s. 2 - check the reverse light sockets to see if they're melted and shorting to ground. I had one do that. Not reverse but a tail light socket. They get crusty and resistive and produce heat.

Did the problem show up immediately after the new fuse box? More detail might help. The wiring diagram doesn't seem to show any connection between the reverse lamp circuit and the brake or gauge lights. They do all have a fuse though. The fuse box seems like the common element. Also, the FSM shows a different wiring scheme for automatic compared to manual. Body Electrical chapter. Accessory Relay and Inhibitor Switch. p.s. do the reverse lights work? They're on a separate fuse right? Can't find an illustration of the fuse box.

Did you see where this thread ended up? Once the thread's purpose is served why not use it to have a conversation? Nothing wrong with that.

Looks like it was stored under a heron colony.

I didn't really pay attention to the two ballast resistor part. Did you buy the car with the Mallory already installed? I could imagine somebody adding a resistor if they thought the module was overheating from too much current. But it's obviously not what the instructions call for. If it was mine I'd probably start from scratch and wire it up exactly like the instructions say, and make sure that all of the connections, including the distributor ground, were clean and solid. And also measure maximum charging voltage at RPM above idle speed. The external regulators can allow 15 volts when they're working correctly and I assume more if they get out of adjustment. Maybe somebody tried a bunch of stuff to fix/bandaid an overvoltage problem then never removed their attempts after they fixed the real problem.

It's fixed. Back to normal programming...

Auction ends in about two hours. Up to $33,333 at the moment. Almost to the $35,000 it didn't sell at before.
