Well, no one came to my aid on this matter so I've solved it as best I could using a metric bolt to replace the missing plastic pin. I measured the left side plastic pin diameter as approximately 4.7 mm. This is close to the 4.7 mm diameter that I measured on a 5M bolt's threads. The hole on the tab on that side of the cover comes in at 5.3 mm so there is about 0.6 mm of "slop" when the pin is in the hole. The hole on the right side tab measured 5.8 mm, almost exactly the diameter I measured for the threads on an M6 bolt. I was a bit squeamish about using an M6 bolt as there would little, if any, of the kind of slop as exists on the other side. So, an M5 bolt it was. I started by creating a small divot in the middle of the broken pin's location. Then, starting with a 1/16" drill bit (Hey, I ain't got metric drill bits), I gradually increased the hole size step-by-step using the next larger drill bit until i finished with 5/32" bit. I then slowly tapped the hole with a 5 mm-0.8 tap. Note that my tap and die set says to use an 11/64" drill for this but I wanted to have plenty of plastic "meat" for the tap to bite into. With that done, I took a 5M-0.8 x 30 bolt and cut off the hex head to give me a crude stud. I threaded this into my hole so that just a little tip of the stud showed on the side where the tab would eventually be. I then put the cover on the remaining plastic pin and, using needle-nose pliers, rotated the M5 stud so it engaged with the tab hole and then a bit more for good measure. I was going to epoxy the M5 stud into place but decided to not do so now at least because things are working well and it will be easy to retract the stud if I need to remove the cover at some point. I LOVE field engineering.

The early 240Z had handed dove tails for the doors, a left and right sided fitting were required. Part numbers R 80530-E4101 and L 80531-E4101. https://www.carpartsmanual.com/datsun/Z-1969-1978/body-240z/body-side-trim-side-window/62 On later cars there were replaced with a symmetrical part that fit on either side. 80530-N3400 Biggest problems with the early ones were the tabs where the screws went through breaking off. Replacement factory parts haven't been available for years. Fortunately I have a set of unbroken originals which we modelled up and reproduced in aluminum. We added an extra 1mm around the screw holes to prevent the cracking and breaking. Just picked up the first samples to fit check and they work just like the originals. The original one is on the right, you can see the slight increase in thickness around the screw holes on the left one. Also modelled up and replicated the original plastic grease reservoir for the steering rack. I'll post details in a separate thread.

I have a correction to the wiring diagram I provided after I cleaned things up a bit and stripped off some electrical tape. The round connection has 3 wires on the harness side and 4 on the ballast/coil side. I've also found that the BW wire that attaches to the + terminal on the ballast had been cut, then twisted back together and taped. I removed the redundant ballast resistor, and soldered the wire splice so it's making better contact. I'm holding off on the suggestion to disconnect the blue wire since I'm trying to minimize the variables when I make a change. In other words, removing the second ballast resistor and improving the wire splice is enough for now. If the problem persists, I'll disconnect the blue wire. I find it odd that the connector eliminated one of the wires. Note: I have a few blank field books from work lying around that I am finding useful for keeping track of issues and updates to the Z. I wish I thought of this sooner. I also found a source of Brother shrink tube that works in a standard Brother labeler. It's great for labeling wires and holds up better than adhesive labels.

Bushings.

I was busy with sorting out some things in life, recently, so no big progress on the Car project side, aside from changing all family cars to winter tires. To keep my spirits up, the postal guy brought new stuff almost daily. The first was a nice delivery of an EU-spec front spoiler and a set of EU-spec front lower corner valances. Thanks a lot @HS30-H for your support, once again! One of them was even a NOS item with the Nissan stickers on it: Then, I also got a small delivery from 240Zrubberparts.com. I was looking for that KM-1520ZC replacement faceplates and I have to say it looks quite good. I was even gifted a set of label stickers for the radio, which I really appreciate. This will come in very handy when come to the planned restoration of the Radio. I hope to be back on the car project again soon. I've discussed a few next steps with a specialist and I hope the project gets a big boost next year, but I also hope to be able to finish a few things in the coming weeks.

Excellent analogy. That's a great philosophical thought exercise. Wonder what the right answer is.........

The first two pics are some 510 4 door outer door/window trim pieces. The second two are 510 2 door outer door/window trim pieces. The rubber looks to be the same shape to me for each of them. The next two pics show the groove on the inside top edge of the door where the inner rubber w/s goes. It is a simple u channel. The last three pictures are of NOS inner rubber weather strips for the 2 door. The front and rear doors of the wagon should use the same inner and outer w/s from a design standpoint, right?

Looks like I have mostly parts candidates in the hoard. None of then work smoothly.

Weak chatbot? Where are the emojis?

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.

Just posted today on eBay. Make an offer? eBayDatsun 240Z 3 Screw Round-top Carburetors, W/ E46 Manifol...Nissan Datsun 240Z Hitachi 3 Screw Round Top Carburetors, E46 Manifold, with Air cleaner. This set up was removed from a wrecked 240Z. These partshave been sitting unused for a while so will obviously

I'm getting very close, one carb at a time. One photo is the view looking down the nozzle, which has been set to 10 turns. Once there is fuel, I can shine a flashlight down the hole and see the level, I'm usually either too high or too low, trying to find that sweet spot. The other photo is the rear float, you can see the weight that was added so when the bowl is at the proper level, the float is level, not canted, where it would hit the ceiling of the bowl. There has been a lot of discussion on that in this thread. One of the photos shows the weights that were fabricated. BTW, although the carbs are from a 240z, they are being installed on a 260z, getting rid of the flat tops. Jim emptech@surewest.net

Well? Did you remember? 🤪

And now he says - I’m out ! I had a hard time reading this guy but don’t think he was ever a serious Z owner/buyer . Good luck - I said Moving on

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.

Killl...kiiilll...KILLLL

That crack is original, not aftermarket. lol

Hahaha! Exactly!

I sold the car and apparently the buyer is sending it to England for restoration.
