Looks like they might be owned or managed by some place called MAPerformance. They can't even get the acronym right. https://www.maperformance.com/collections/itm-engine-components "...For the best selection of engine management parts from ITEM..."

I don't know who ITM used to be but it looks like maybe only the brand name persists. They don't even have an open web site. Many/most of the old performance part names are just brand names now owned by large conglomerates that source manufacturing to the cheapest bidder. https://www.linkedin.com/company/itm-engine-components http://itm.openwebs.com:8080/

How do they perform if installed correctly? Just curious. Is it a quality problem or a following-instructions problem?

Where did you see the bad information?
-
Download the service manual and open up the General Information (GI) chapter. It shows where the various numbers and tags are. I've found though, that some sections of the chapter, at least for the 280Z's, seem to describe a plan that never actually was completed.

Some summertime vibe music.

@Pat Horne Good luck.
-
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.

One the "The 240Z Guild" cars is up on BaT again. It was sold on BaT in 2017 by The Guild then "reacquired" by The Guild in early 2019 then sold on BaT again in 2019. Now it's up on BaT again. https://bringatrailer.com/listing/1972-datsun-240z-29/ $26,500 https://bringatrailer.com/2018/01/13/bat-auction-success-story-regrets-reconciled-with-purchase-of-1972-datsun-240z/ Success story https://bringatrailer.com/listing/1972-datsun-240z-108/ $50,000 https://bringatrailer.com/listing/1972-datsun-240z-362/

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?
