Well, if you wanted to take advantage of a bunch of somewhat bored (COVID captive) people who can generate a bunch of ideas you might just describe more about what you're working on. It's one reason the site is popular, from both sides of the situation. We like a puzzle. Just seems like a "not the bushing' situation. There are other things that leak back there that seem like the slip yoke seal but aren't. You still haven't said if the slip yoke is loose in the bushing.

Is the yoke loose in the bushing? Maybe your tail housing is cracked. Good luck. Not really seeing a new bushing as a solution to your problem if the yoke isn't loose in the bushing. What does this actually mean?

Still not clear why you're looking at the bushing, for an oil leak. There are actually grooves in some bushings to let oil pass by. It's the seal that contains the oil. You can replace the seal without removing the transmission.

Since it says 1977-up, and the 4 speed part shows discontinued, I'm going to guess that there is something different about them. I'm pretty sure though that somewhere in past posts people have found a substitute bushing. Worth some searching. https://www.nissanpartsdeal.com/parts/nissan-bushg-extrr~32132-78000.html

My first thought was yes, but the parts website doesn't show a bushing for the 5 speed. Not sure why. A leak would be the seal though, probably. If the bushing is bad the slip yoke will have excessive play. http://www.carpartsmanual.com/datsun/Z-1969-1978/power-train/transmission-case/4-speed/from-sep-71 http://www.carpartsmanual.com/datsun/Z-1969-1978/power-train/transmission-case/5-speed

Another thought - you could take a portable drill and a piece of hose and use it to spin the input shaft at high speed. Listen for noises and look for wobbles. After I bought a mystery 5 speed I hooked it up to a spare engine I had that I had running on a stand (Harbor Freight dolly). I put some used fluid in that I had kept and ran it through the gears on the running engine. It sounded like a blender and the fluid came out looking like silver metal flake paint. A drill motor and a piece of tube might get similar results. With no drivetrain load on the output shaft you can shift gears without worry. Even with no fluid you can still get an idea of the quality of the parts, if the seller will let you do it.

You can remove the drain and fill plugs and maybe some of the switches and look inside at some of the synchros and gears. But I found that even a transmission that was extremely damaged, with broken shift forks and synchros and bearings, would still shift through the gears and the shafts would turn. Kind of like you found with the one you're replacing. It's difficult to tell until you get it apart. You have to use your ability to judge character I think, and the various internet tools. I don't know how the FB marketplace works. Does the seller have a visible profile? A way to see opinions of them and past sales? I bought a whole non-running 1978 280Z in the past, just for the transmission. Probably the best buy I ever made. The engine was good and it ended up in my car too, along with other parts.

How about the other stuff? Might also be that your idle speed is just too low. The alternator/crank pulley ratios are not quite right on the Z's. If they'd just made the alt spin a little faster, many problems like this wouldn't be around. An extra 100 RPM of idle speed can make a difference.

The guy screwed up his numbers. Might be off the radar.

https://www.theguardian.com/society/2021/jan/18/almost-30-of-covid-patients-in-england-re-admitted-to-hospital-after-discharge-study Nearly a third of people who were discharged from hospitals in England after being treated for Covid-19 were readmitted within five months – and almost one in eight died, a study suggests.

You must have contacted the wrong "Motorsports". They made quite a big deal out of reintroducing them to the Z cars. Just the word Koni should have been enough to get you set up. p.s. seems like these should really be called a strut component, or strut shaft, or strut member, or strut shaft shock member. Without it there is no strut, but it's not the complete strut.

The relay locations are shown in the Body Electrical chapter. The 260Z has the inhibitor relay also. https://www.classiczcars.com/files/category/12-260z/ The wiring diagram will have wire colors which can help. https://www.classiczcars.com/files/category/1-wiring-diagrams/ Some of the relays and devices have numbers printed on them.

$132,000 for the Pantera. There's a video but the guy never really got on it, unless I missed it. I FF'ed through parts. Drone....

$26,250 for the Honda with the motorcycle carbs.

Not a Z or a Datsun, might be pretty fast. https://bringatrailer.com/listing/1974-detomaso-pantera-26/

Not a Z or a Datsun, probably not very quick (0.8 liter engine) but kind of neat. https://bringatrailer.com/listing/1970-honda-s800-coupe/

Going for the perfect rear wheel bearing install. Karma says you'll slide in to a curb on your maiden voyage. Just kidding! Did you examine the old bearings for damage? Wondering what was making the noise.

My thought was more about "what now" after they got in there. Even if they accomplished their "mission" and there were several dead politicians scattered around, then what? Occupy the Capitol building? I lived in the Portland area when the same type of people "occupied" the Malheur Wildlife Refuge buildings. All they did was camp out there for a little over a month, but accomplished nothing. Same type of scenario, use their guns and take over a tiny spot on the face of the globe. For what? The wild west isn't wild anymore. That stuff doesn't work now. https://www.oregonlive.com/portland/2017/02/oregon_standoff_timeline_41_da.html

Mistake.

*sigh*

Mistake. Sorry to the guys that "reacted". I spit the hook.
