The front struts have a bearing under the isolator. Part #53 in your picture. I assumed that this was about the rears because no bearing was shown or mentioned. Anyway, some good leads to follow.

Part 13 is below the insulator. It is small. Part 46 from SteveJ is a large part, apparently for a Nissan Pathfinder. Not sure if he's recommending an alternative. ??? There are aftermarket bump stops. But they are placed aorund the sliding strut shaft.

What is the purchase procedure?

Might be the "spacer". Part #13. I actually bought a pair for my car from Courtesy Nissan long ago. Not sure if you can find them now. It's just a hard rubber ring. Datsun Z Rear Suspension (Strut,...Datsun Z Rear Suspension (Strut, Shock Absorber & Transve...

Looks like the advertisement area doesn't work anymore since Mike updated the software. @kickstand80 should be notified by your response but just in case, the @ function should do it. He hasn't been on the forum since March 19. Pretty sure I've seen him posting over on zcar though so he is still around. @Captain Obvious might have a spare from his testing if 80 doesn't have any. Good luck. Would have been neat to see one in action via some sort of video.

Did you replace the factory diff mount? When you use a bumper with the RT mount it essentially just replaces the strap. It reduces upward movement but the diff can also move downward if the stock mount is worn. Also, the bushings and bumpers on the ends of the mustache bar look worn. If you crawl under the car and grab the mustache bar end with your hand you'll be surprised at how easily it can be moved up and down. New bushings might help, although sometimes they can bring some diff whine in to the cabin.

Darn it, you locked in my grammar error. One the. It has the same mileage now as when it had dual filters. That's good, for the engine.

Do they always spin opposite the direction of rotation? Like the wheel is leaving them behind? Maybe they're actually "walking" due to vibration or flexing. That might show as unexpected spin direction. I have a board in a floor that slowly opens a gap on one end after many months of traffic. Must be something about the bumps on the bottom or in the groove that ratchet it over. I kick it back in to place with my foot and it slowly works its way back open. If the caps are walking you might be able to twist the clamping portion so the teeth aren't biting. Can't remember exactly how they clamp to the rim. I assume that you know they're spinning because the valve stems are suffering impingement.

Almost 100% sure that the Nissan OEM pumps used the cast impeller, not the stamped steel. There are extensive discussions out there about which pumps best. So, I don't know if A is correct but I'd say that B is definitely incorrect. They both look pretty nasty. Are you thinking about using one of them?

Interesting that the 1978 260Z, U.K. version shipped to Australia, referenced a few posts back also has the bumper mounter signals even though the grill with the signals inset was introduced in 1975 in the 280Z. I guess that Nissan had a good thing going and just let it ride. Or maybe the big bumper grill didn't work with the small bumper. Or the new signals were still too hard to see. The height seems right.

Are these turn signals normal? They look pretty weird. Other markets got the inset signals?

Where did you get the parts? The grease is for inserting the seal in to its groove. Brake fluid is for sliding the piston through the seal. Oh well, the cars wouldn't be any fun if there wasn't something to fix on them.

Pretty cool. Odd that there's no fan shroud. Maybe because it doesn't get that hot in the U.K.? I've heard/read about the carb'ed European 260Z's, still around after EFI was introduced in the States. Never seen one.

If you have a caliper on the bench you might as well pop the piston out. Don't scratch the cylinder with the metal dust seal retaining ring. Images won't load but the Brake chapter describes it. Uploading Attachment... Uploading Attachment...

Not sure what you mean by two pieces. But if it's sitting on the bench then, obviously, there's an open port to atmosphere. No way to hold pressure. The piston should be easily moved by hand if the caliper is new or newly rebuilt and has had fluid in it. Or maybe not, re above. Where did you get the calipers? Might have a bad rebuild. Tight seals.

Opening the bleeder when the brakes are stuck will tell you if the problem is pressure in the caliper or something else. If there's pressure in the caliper you can work your way back to the the MC fitting by fitting. Or work your way down, from the MC. First you need to know if it's hydraulic pressure or just mechanical sticking.

Probably worthwhile to read the Brake Chapter. It's not long. Well-illustrated.

But, don't overlook the brake pressure warning switch. Or the NP valve. Can't remember the car. (https://www.classiczcars.com/settings/signature/) It can get gummed up also. Uploading Attachment... Uploading Attachment...

The Nissan calipers use the rubber seal to retract the pistons. One common cause of sticking caliper pistons is collapsed rubber hoses. The MC can generate high pressure to push through the collapse but the rubber seal cannot to allow the pressure to release. It becomes like a check valve. On some cars the cause is a metal clamp on the hose that rustjacks and pinches the hose. But just degrading internal material can cause it also. I ould guess that a kink in the hose could cause it also.

If you can do this when the brakes are stuck it will tell you if the rod from the booster to the MC is too long, causing the return port in the MC to be blocked. You'll have to do it while things are still warm though. Patcon is implying that the air expands as it gets warm creating pressure in the system. They make a tool for setting the booster rod length. It's a fairly common problem, especially with rebuilt boosters. If you stare at the parts long enough you can figure out other ways to get it right.

I had a 1978 igntion switch with that problem. I was able to fix it by restaking the copper contact with a chisel. You'll need to remove the switch and disassemble it. Or, it could be that the mechanical portion is worn and not turning the electrical contact far enough. I fixed that on my 76 by putting some extra twist in the rod between the mechanical and electrical parts. Once you get the switch out and examine it you can test either possibility with a meter. Stole this from ZCarDepot to show the staked contacts. https://zcardepot.com/products/ignition-starter-switch-240z-260z-280z-510 And here's the back side where the rod inserts.

It might help to add some detail about what this means. Are you saying that the starter does not spin the engine? It's just click, click, click, then spinning happens? Also, watch your gauges and the ammeter. If they all go dead, then come back to life that's a sign of a bad battery cable connection. The heat from the starter motor draw causes the bad connection to expand and open. Then it cools and closes. The small spade connection at the starter solenoid can be loose also. Same effect. I almost replaced a starter once, but instead just repinched that connector. It was loose.

The seller said he could see holes for an AC system. So he assumed that it had had AC. Who knows. It almost broke 100. 95. The winner didn't play the small bid game, every bid was a big jump. https://bringatrailer.com/listing/1970-datsun-240z-133/
