And...off she goes, back to the owner. Will post overall summary and lessons learned once I get a little time.

Here is a link and one of the last known pictures of one Yuasa N50

Thanks for the comments everyone. Still waiting to hear from the transportation company on the pick-up date. Should be in the next week or so. The owner is having Intercity Car transport (http://www.intercitylines.com/) do the pick-up and transportation, so looks like we are in good hands here. They are Jay Leno approved .

Had a nice sunny day today, so I backed the car out for a couple pics.

Got the new antenna parts in. The originals were cracked and oxidized so picked up the new parts from http://www.240zrubberparts.com/. Pics below show the old antenna parts and then one with the new parts.

This won't last long if it is legit. https://sandiego.craigslist.org/csd/cto/d/1972-datsun-240z/6485937019.html

I am guessing you probably just adjusted the air flow per the video. Ztherapy sets the standard mixture flow to two open turns, which is probably how you received yours. My set from ztherapy was set the same way and car ran like crap at the high end and on acceleration. I opened the mixture dial one more turn (three turns total) and the car now runs perfect. Each car is different and one size does not fit all. I still think it's carbs.

This is what I think will happen when you replace the oil pump..(see quote below) Your problem is most likely carbs

Just my opinion on a couple things: 1) I doubt that the oil pressure is the problem with the accelerate and idle problems. Sounds like carb adjustment to me. Also, could be fuel vapor lock issue. 2) I don't really trust the oil gauge value on the 240Z gauges. You would probably want a direct pressure gauge to the block oil port to measure real values. 3) If I did contact the seller, I would ask what rings and bearings were installed. Does he have the receipts. these parts are as important as the head items if not more. 4) probably not worth the time and effort to sue if you do not have direct oil pressure data 5) Not sure what disassembling block would do for you. Just change out the oil pump if you are concerned about it's integrity. Much cheaper and easier.

Hmmmm, need to install those two bolts on the lower bell housing. Pics are always good for stuff like that. Also need to add the black paint to the muffler tip. Will take care of that tomorrow. Here are the latest motor pics. Got the final decals on and voltage regulator cover.

Exhaust 2.0. This is so much better. The resonator is tucked up there nicely.

Interesting topic regarding sound deadening material selection. The short answer is that I selected the Noico because it was used and recommended by others on this site. As a mechanical engineer who has worked extensively with noise reduction and sound deadening applications, I think that it would be difficult to rate one brand over another without actual side by side tests performed with the correct measuring equipment on the actual parts in question. You cannot compare a Ford truck door with a Datsun 240Z door. The door panels will have different resonant frequencies, thus different sounds . Material Mass and energy absorption are key as are thickness and dampening. The dampening will be affected by the size, mass, stiffness and thickness of each individual panel. That being said, what may work well in one application may not work as well in another application. I really could go on for a while on this subject but will stop here. That being said....I did not perform any technical studies on 240Z's with the materials available and cannot knowingly state that the product i used is the best in this application.

No Prob....it's always good to have a little diversion. Got the luggage straps in and rear panel installed. The interior is pretty much done except for those two little hatch plugs (should be on their way here from Banzai Motorworks). Took one more pic of the car in my garage. It is starting to hit me that the car will be leaving soon. It actually makes me a bit sad. I often walk out into the garage just to look at it. At this point I just have a few parts that I am waiting on but those should be in soon and quick to install. Then a few little adjustments; the brakes squeak and the carbs need some minor tuning and then she is ready to go. Hard to believe that it is just about complete. It has been quite a journey.

I did exactly what @siteunseen mentioned above. It looks great and is the closest I have seen to the original. Although, I did use the 'Bulldog Spray adhesion before the paint coat.

Yes, this really was a tough choice. I talked with my paint guy at length about the two options. We went with the two stage in order to have a more durable finish and simpler touch-up if needed. We also wanted the paint to really shine and standout. Durability is also why most of the undercarriage is powdercoated, the underside is POR-15ed, and I put clear coat or matte coat clear over some parts (like aluminum). Otherwise, in 4 or 5 years the process needs to be repeated. Ideally, it would be nice to have the restoration look perfect for another 40-something years.

Yes, the larger black piece that looks like a dome is plastic. The rubber disc shaped piece is below. The plastic part tends to disintegrate and the rubber piece hardens. The parts that are below the body are usually in great shape since they are not exposed to the elements. It's just those upper parts that are a problem.

@nix240z: Would be nice to get the rubber/plastic below that as well if available. Time takes its' toll on plastic and rubber.

@nix240z: Yes, I will pick up one as well. I would be hesitant to get a used one as I am sure the plastic is incredibly frail, like my current one. My current one is like eggshell, and is held together with super glue.

I could use one of those finishing nuts as well. Did not see any on @nix240z site. The nut part on my antenna is fine, its the plastic that is not good.

Well, things are getting close to the end here. Still waiting on a few parts to come in and the revised center section of the exhaust to be completed then she will be about ready to go. Miguel came over today and did the final polish on the paint which actually looked pretty amazing before he even started. After about 6 hours of polishing with three different compounds and pads, the paint is absolutely incredible. Not a single scratch or swirl to be seen. There are a couple pics below, but they do not do the paint justice. I will have to wait for a nice sunny day and take some pics here to really show the quality of the paint job. While Miguel was doing the polishing, I painted the rear carpet which really looks great. I was a little skeptical of how it would look, but it really looks like new carpet. I should get the new luggage straps in from Jay in the next couple days to complete the back hatch area. It should look great once these are in. Also got the hatch plugs coming in as well. Got the horns refurbed and installed. Also put in the final fender screws and touched those up with paint to match.

I finished the hubcaps and installed them. Also put in the new speaker. Took the car out for a small photo shoot. For some reason I thought the best conditions for photographs was with over cast skies, but I don't think that is the case here. Everything reflects off of the paint. Should have taken the photos when it was sunny..I guess. As you can tell, I am not really a skilled photographer. Anyway, here are a couple pics.

Yes, she's a beauty! Very well preserved. Original equipment is always very nice to see.

Around 4 years and no cracking. The initial paint that was sprayed by the shop directly on the urethane and started flaking off in less than 3 months.

I sanded the urethane air dam with 600 then 1000 grit. Then sprayed on Bulldog, then sprayed on final paint. No primer

I used Bulldog Adhesion promoter on my Yellow Z urethane Air dam. Works pretty well, much better than paint on plastic. https://www.amazon.com/ADH-PROMOTER-15OZ-AERO-KLE-ETPO123B/dp/B005IUBMS6/ref=sr_1_1?ie=UTF8&qid=1515617607&sr=8-1&keywords=bulldog+adhesion+promoter
