While you have it open, you can suck on the vac advance rubber hose and make sure the advance is working properly. Plate should rotate and return. I dont think that's your issue but gives you some piece of mind that advance is working. Replacing pertronix (as Patcon suggest) is easier than removing the head.

No, I would just make sure that the shaft doesnt have any play (wobbling around). Remove the cap, remove the center rotor (part that spins), then wiggle the metal shaft left and right. If it does have play, then you have issues with the dizzy bushings and it needs work. It will have play up and down but should not have play laterally. Take the #4 plug wire and swap it with the #3 plug wire. Swap them at the plug AND the distributor cap. If your fouling plug moves to #3 then you have an ignition problem, if it doesnt you have a problem somewhere in the motor.

I would eliminate everything I could before pulling the head, especially since you have good compression, no smoking and no signs of a bad head gasket. You may want to remove the rotor in the dizzy and check the dizzy shaft for play. It should have no play. If it has play that can cause inconsistent firing. I dont know if it could cause a single cylinder to always missfire or how a pertronix would be affected. I do recall you getting better running when you were messing with the ignition wiring. Maybe swap a plug wire just to be sure it isnt one of the wires.

Maybe glue a thick piece of rubber to the top to cushion the speed shift!

I used this BAT auction car for a lot of reference pictures. Lots of detailed pictures. https://bringatrailer.com/listing/1971-datsun-240z-124/

It isn't too bad of a job. When I was young we used to a few pieces of heater hoses to hold the chain in place! Take your time and dont forget the two front bolts on the head. I hope you find something wrong 🙂

1,800 and 6 months.

Tri city plating did mine. It was expensive and took a long time, but they did a good job.

Looking great. Its game on now. My defroster hoses had been modified by mice. I got some decent replacements from datsun rescue. I need to go through my "extra" box and get you some pictures to see if you can use any of it.

There has to be a reason its 400 more. Looking at the pictures on the websites I noticed that the Vintage dash has the metal integrated into the center dash area and the datsun garage one doesn't seem to have that. Maybe call vintage and ask why you should buy their dash. Still cheaper than I paid for Just dashes. Your car is going to look great.

sorry....

Agree with Patcon, I think you will have a big mess. If something doesn't go right (crack) and the glass has to come back out, thats going to be a disaster to clean up. Here is a video of a guy that put sealant under the lip after installing the glass. Personally I would install it dry, and if it leaks then add sealant. https://www.google.com/search?q=youtube+installing+datsun+windshield&oq=youtube+installing+datsun+windshield&gs_lcrp=EgZjaHJvbWUyBggAEEUYOTIHCAEQIRigATIHCAIQIRigATIHCAMQIRigATIHCAQQIRigATIHCAUQIRifBTIHCAYQIRifBdIBCTIyNTE3ajBqN6gCALACAA&sourceid=chrome&ie=UTF-8#fpstate=ive&vld=cid:9b4f37af,vid:H77PZfCmwcU,st:0

Got some round LED's and made some floor lighting using the OEM wiring. I mounted them with some pieces of aluminum and used 3M emblem tape to hold them in place. I got the lights from amazon. Very pleased. Thanks @zKars for the idea.

Dang that sucks. I used just dashes. Took forever to get it back but I was pretty pleased with their work. Like inline said, the gauges did fit tight. It looked to me that they replaced the entire foam as they repainted the whole frame and all the foam appeared fresh. I got a local shop to get a new windshield. I think it was around 250 or 300. I guess I got lucky putting it in. I really lubed it up with some silicone rubber lube. Gasket and frame. I remember thinking, this thing is too big to fit when I got up to the top. I just kept pushing it down and went slow. Are you using an oem gasket? Maybe the old windshield was just brittle. I have two spare windshields ( not OEM) if you want one. They are in ok condition. I guess the silver lining is that you broke it and not your helper. Glad to hear you are making progress!!

That's code for "Made in China"

Thats a great idea. I saw the two wires taped to the harness tonight when I was installing the LED flashers. It would be nice to have some light in the footwells. I have plenty of JDM style connectors I bought when I was rebuilding the harness. It would be easy to rig them up. Here is my flasher relay installed (note the proper connector for the ground). I used some 3M emblem tape and left the OEM flasher in place. I like being able to adjust the speed of the flasher. Now if I would have ordered the correct color 1157 bulbs, I would be all set.

I think I can live without them!

@SteveJ I cant imagine trying to figure it out if you didnt know some of the z history. In the diagrams I see a "Step Lamp L.H. and Step Lamp RH". I guess they were some kind of other interior light for JDM?

I guess it would help if I had the right wiring diagram for my year! 3/72. My seatbelt buzzer and key buzzer are the same (no key buzzer on steering column) and the buzzer is near the fuse box. The wiring diagram I have is for an early model without the seatbelt light. At least now I have a fighting chance.

I bought the same struts from Rock Auto June 2022 and I dont think I had that problem. That is something I would have remembered for sure! I think I would try and contact KYB, if that is possible.

Thanks, that is a new switch and works the interior light properly. I think to properly diagnose it, I need to review the wiring diagram and test the wires on the switch and steering column. I just have to get motivated to lay under there. It isn't getting under the dash that is the problem, it's getting out!

My have been wired differently in 73. My buzzer is disconnected, as I think there is an issue with the ignition buzzer switch. It buzzes all the time the key is in the ignition and on. No matter if the doors are closed or car is running.

I ordered the ones in Steves post. They have three prongs and an adjustable knob. I will play with them and see if they work. Should be delivered today. I may end up with the ones you posted. Thanks for the link.

Thank you @SteveJ, I got some ordered. I appreciate your help. All my dash/interior is LED, so I just need to concentrate on exterior.

Thanks, I will try and find the thread.
