@cgsheen1 Maybe you can help with my tach. After my mechanic did my zx distributor in my 240Z all was well for some time so I guess it's wired correctly. Then one day I was out for a drive and watched the tach all of a sudden start climbing and in a few seconds it had gone all the way over to 8. I shut the car off and sat for a minute then started it back up and ever since it doesn't go above about 3500 RPM. My ballast resistor is removed. Other than that my car runs just fine. Any ideas, maybe a coil change? There's no marking on my current coil so I don't know what ohm it is.

@Captain Obvious What is the build date of your car? Is your map light in the dash hooded? I ask because there are a couple of us with pre HLS30-21000 that have hooded map lights. The hooded map light is one of the things that Datsun stated would be updated for the 21000+ cars.

Here's the fuse block Cover from my 12/70 car 17486.

You didn't mention which TachMatch Device you installed? I did a ZX matchbox distributor with removed resistor on my 12/70 car. My tach almost works but doesn't seem to go any higher than about 3500 RPM.

Wondering where you've installed the obligatory rust on "Lilly" ?? 😉

Took the Z to a show at a local Chevy dealer. When I pulled in the dealership owner said "We never see these cars, I want you parked at the entrance".

A very early AI movie (and there's a trilogy of 3 books) is "Colossus: The Forbin Project" released in 1970. And yes, we lose control of it.

I never lock my 12/70 240Z. It's garaged almost 100% of the time. When out it's for a show or cruise night or visiting friends. There's nothing in the car that really worries me and I'd rather have it just stolen than having someone break a window to get what they're after!

Is this like Datsun saying the hooded map light was one of the changes for 21000 and beyond yet 2 of us with 12/70 cars have hooded map lights. I would think it possible for Datsun to document zinc if that was the direction they were going but I could also see them using up cad NOS if they had it.

Then I would guess that with the electronic flasher it makes no difference since it's not load related. And in the case of my all LED bulbs the load (even with all 8 hazard lights blinking) is insignificant.

I left mine blank, but I don't have driving lights. I did repurpose the slot for the manual throttle next to the choke for the antenna switch when I swapped out the stock radio back in '91 for a Sony cassette player that I've now replaced in 2017 with a RetroSound Bluetooth radio. Our son 3D printed the faceplate for the radio with the raised lettering and the surround of the radio face that I painted white so it has a more stock look.

@WJ4Fun When I did the LED conversion on all my lights I used the same flasher for both blinker and hazard lights and both work just fine. No idea why Nissan would have different part #'s for the flashers.

Here it is over hiding against the passenger side relays just behind the vent pull rod.

They've added some pictures for the "barn find". The steering wheel is not from a early car, it has a cap on the dash, caked sludge on the oil pump, you can see rust in the picture looking down on the driver rocker... Engine bay is also in the new pictures, pretty scary looking.

Stevej's recommendation for LED bulbs is spot on. I would go so far as to recommend all external bulbs be LED. If you do that be sure to use colored bulbs that match the lense color they go behind. And you will also need to replace the blinker and hazard flasher with electronic units which are available on Amazon. I used these. https://www.amazon.com/Hbxdeco-LED-Flasher-Relay-Replacement/dp/B0DBQDY9PX/ref=mp_s_a_1_4?c=ts&dib=eyJ2IjoiMSJ9.r0vtsr6gvhaP0JqIkrNNWe1VSyoKzqOmRDZMqIRm6Sx2S7hdmByoSlq5B7nnOyC4MjUdGvYR06DT5etEUXNzrXbi7AcSH8Rng3yRz4GSf1YwuYjEHcbLtbKRPcP3uDHyo1Fn9msBVau9Fk45nP6kIF-9rnZd6556d6neZaina6L_ZLR8n8uvVl9wvzzTfmPOdAe6JyV2wZsad-_tpTWpyg.1qmzhFAIKk5rXUhbY14Gkd6aGisVISftIH7AlWO7sMs&dib_tag=se&keywords=Automotive+Electronic+Flashers&qid=1756048201&s=automotive&sr=1-4&ts_id=15716621
