It is a cool image but what am I looking at exactly?

Looking good! Hope to admire your Z sometime in the future. I’ll be visiting Mart with my 280z this weekend to admire his ZX and rummage true his parts pile. And most importantly picking up a replacement 5 speed gearbox for the Z with the Z. The second gear syngro is busted and fifth gear is currently a neutral. 😅

I was having some trouble with the AFM on my ’77 280z a couple of months back and compiled some of my research int a post here on ClassicZcars. Maybe it’s an interesting read to help you along or have trouble again in the future. Baseline was that the car ran rich no matter what I did and along my journey I replaced every sensor before finding out the carbon tracks inside the AFM had breaks in it. I ended up replacing mine with a 7 pin AFM from a 90’s Ford probe / Mazda 626. That AFM is a bit bigger then the stock Datsun unit but the rubbers will fit over it and tightening the spring a couple teeth brought the AFR readings back into spec. the car still runs a little rich on idle but the emissions where pretty low for a late 70’s car and she drives perfect with good AFR readings while driving.

Now that is an interesting power steering option! Those Opel Corsa C’s are everywhere over here and you can get a complete power steering column with the computer from a junkyard for under €80. What modifications did you have to do to make the Corsa steering rack fit the Z or does it just bolt up? I imagine you replaced the Datsun steering shaft with the Opel/Holden/GM one or did you have to source one from a different car? Would you be willing to share some of the part numbers you yourself used? That might make a nice reference point for people in the future.

Look up M539 Restorations on YouTube, he restores and refurbishes BMW’s to absolute factory or better then factory spec. He uses a water blasting machine (I’m sure there is a better term for it) to clean all the parts and mainly aluminum engine parts. I’m not sure what exact product he uses afterwards but after basting he brushes on a protectant on the aluminum parts to keep them from corroding over time. Give it a look, I’m sure it would be a great product to help protect your carburetors.

After getting my 1977 280z past it’s last inspection ever and back on the road, for the first time since owning it, I took it to work to see how she drives. And man the engine feels great and incredibly healthy. Unfortunately the alignment was incredibly bad. I had her aligned during the inspection and the guy said het put everything to zero as a baseline but the car was all over the place and was very hard to turn to the right. I took it to a tire shop very close to work since I know they also do custom suspension and alignments for high performance racecars. And my god the previous guy messed up bad. The alignment wasn’t even close. Below I’ll add the alignment sheet with the terms translated to English, please note that a -0.67 degree toe means a toe out of 0.286 inches which is massive for the front wheels. The car drives a lot better now even though the rear is still off. The front office didn’t quite get what kind of car I was bringing in and just how custom the suspension (full Apex Engineered control arms and front crossmember) was and thus only scheduled a standard half hour alignment. I’ll be adjusting the rear trackwidth myself so I’ll unlock more rear toe adjustment and then pop back into the shop for a final alignment. After that I’ll be saving up to refurbish the shock absorbers as the rear once are totally gone. Eather that or a set of Intrax or KW coilovers. But the most important thing is that I can finally enjoy this beauty!

Yes, I’ll be in touch to come visit. I’m currently very busy with my garden as they will be laying the new tiles next week but I’ll come by at the end of this month or next month.

Small follow up. The “new” thermostat housing arrived last week and after a quick paint job I installed it with the sensor that broke my previous housing. This time nothing bad happened and my gauge finally worked!

Nope, she drove fine and even passed inspection! This means she is finally road legal again! Fun fact, as the car is form July 1977 she will be 50 years old next month and thus doesn’t need it’s mandatory yearly inspection anymore. This means this was the last mandatory inspection of her live!

I should get the replacement housing in somewhere in the coming days. When I do I can investigate properly what happened. I didn’t use too much force and the socket wasn’t pressed against any of the other sensors. It might actually be a casting fault from Datsun/Nissan or galvanic corrosion as the sensor looked original and probably was never replaced before. Also one of my local club members noticed a crack at the same place mine broke on one of the 280z housings he had lying around.

As my 1977 280z is all back together now and almost ready of inspection I decided to replace the temperature sensor for the gauge in the dashboard as it wasn’t reading anything. The old one came out pretty easily and was very corroded so no wonder the gauge didn’t work. While installing the new sensor I apparently torqued it a little too much and broke the housing. I didn’t even use much force so I was pretty surprised. I first thought that I might have stripped the threads but no, I took a chunk out of the entire housing! Have any of you seen anything like this? P.S. I already sourced a new housing through my local Z club which will be coming in this week.

Well the car is back together and I still haven’t found where this bracket belongs. 😅

I checked the screws on my seat mechanism cover and those too are ether M3,5 or something imperial. Bit strange as those screws are fairly rare even here in Europe.

I will check back home for you as I just took my 280z seats apart but I bet they are just standard metric M3 (3mm) screws. Even in the US they can’t be that hard to find I would think.

Language is a funny thing. I didn’t even notice it as I just read past it!
