That's not what you said in your first post. I think that your friend is irresponsible and should be reported for spreading information that is counter to CDC guidance. He's not the President of the United States. Even if he thinks he knows better it is irresponsible and dangerous to suggest that the organization that he works for is giving illegitimate guidance. It puts everything the CDC is doing in to question. That's where I'm coming from. https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/diy-cloth-face-coverings.html CDC on Homemade Cloth Face Coverings CDC recommends wearing cloth face coverings in public settings where other social distancing measures are difficult to maintain (e.g., grocery stores and pharmacies), especially in areas of significant community-based transmission. CDC also advises the use of simple cloth face coverings to slow the spread of the virus and help people who may have the virus and do not know it from transmitting it to others. Cloth face coverings fashioned from household items or made at home from common materials at low cost can be used as an additional, voluntary public health measure.

I've posted this before. I read the work of the professional scientists and trust them. Not the words of somebody who sounds confident, for no apparent reason. Why would you pass on the words of somebody with no reason to know more than the professionals? How can you "not care"? Really, what was your reason for posting that pseudo-knowledge? Doesn't make sense. "A guy that works at the CDC". Could be a security guard. Would you trust him to treat you if you had COVID-19? That's the problem with being "rational". You can rationalize anything to make it sound sensible. Here's a good one - sunlight kills the virus. Therefore, if you're out in the sun you can't get it. Everybody should, therefore, go outside. Where they'll be safe. Makes sense? And, on pseudo-experts. What happened to hydroxychloroquine? https://www.politico.com/news/2020/04/20/trump-hydroxychloroquine-coronavirus-196191

I'm still waiting for gas prices to drop here in Washington, even though they should be paying me to fill up. https://www.theguardian.com/world/2020/apr/20/oil-prices-sink-to-20-year-low-as-un-sounds-alarm-on-to-covid-19-relief-fund

BRAAP is Paul's screen name on Hybridz.org. You used your real name but most people come up with some sort of clever internet name. "BRAAP" is the sound a race engine makes, so that's the name Paul chose on Hybridz. I think that he also had an engine-building business for a while, Ruschman Motors, or something like that. Here's his profile from Hybridz.org, and a page he made about one of his cars. Hybridz.org has slowed down a lot since Paul was active there. p.s. when you reply, write outside of the box of the quoted material. https://forums.hybridz.org/profile/16-braap/?tab=activity http://www.datsuns.com/projects/paulrproject.htm

Paul Ruschman is BRAAP over on Hybridz. He's been more of an EFI, fuel injection, guy over there. He's been out of the Z picture for a few years, not sure why. Sounds like fun.

What does he do there? Is he a professional? I ask because there are professional viroligists who determined that face coverings were helpful. I've worked with many people who were at a high level in their profession but understand very little about mine. I've posted about the problem of being a smart person in the past. If you know a lot about one thing you start to believe that you know a lot about everything. Need some background on your friend's area of true expertise. p.s. also, it seems that your friend might be confusing areosol with droplets. Droplets are projected from the mouth and nose, hence the value of a face covering. Aerosol is what the best masks are designed to prevent. I think that you can argue about aerosol, but not about droplets. Your friend sounds like someone who wants to be someone smart, but is giving you bad information as a result. And now you are spreading tit. Finally, if your friend has any influence at the CDC why are they publishing "incorrect" guidelines? Why does his opinion have no value at the place that he works? . "Works at the CDC" could mean almost anything. Don't be part of the misinformation problem.

Oops, I didn't read the full message. Things have slowed down, forever. Datsuns Northwest has closed their doors. Not looking good for car clubs. Maybe the Seattle area. But it looks like somebody will be organizing the occasional cruise or meet. So, keep the site in mind. Probably these guys, Datsuns Northwest. I never joined but the Canby show was/is always a big deal. Things have slowed down a bit since I got in to the game but that doesn't mean they'll stay slow. Worth a look. http://datsunsnw.org/

If you swap them the bleed screws will go to the top. If they're on the bottom that's your problem. It's a common problem.

Check the bleed screws. Pretty common for people to install the calipers with them on the bottom where they're easy to reach. But they need to be at the top where the bubbles are. The calipers can be swapped.

Makes sense. Nissan used the N47 head on the N42 block until they changed to the F54 block in about mid-1980. Nissan did do some odd things with the cam lubrication though in 1977. They switched from the spray bars to the internally oiled cam. Make sure that those parts are right. Carry on.

A house divided. Competing with, probably, Jared Kushner, Or Jared is actually the drug dealer making the deal, controlling the market. Get your own PPE! https://www.nejm.org/doi/full/10.1056/NEJMc2010025

Only the engine block can be matched to the chassis and that is only up to 1976 (maybe 1977), Nissan put the engine block serial number on the ID plate by the brake master cylinder. Either the N42 or N47 head will work exactly the same on the N42 engine block. But the exhaust manifold for an N47 head does not work well with an N42 head. So that's really what you need to match, the exhaust manifold. If you have an N42 head with a square port exhaust manifold it will bolt right on to the block and work fine. Your mechanic should know this. p.s. 1977 was the year that Nissan changed from the N42 head to the N47 head. So you could have either. Your mechanic might be looking at some sort of database and using 1977 as a guide. But the N42 head is found on 77's also. Just rebuild that N42 head and use it.

It's just math, time and understanding. New is easy. I screwed up in my first post because the rotor is separate from the hub. I was thinking of other cars where they combine the two.

Thanks HS30. Looks like one of those companies that split off a division or two. It's what big companies do. It's hard to tell who's who sometimes. Surprising that it broke, but who knows what abuse it might have seen. http://eac.exedy.com/eac/company/history/ https://www.exedyusa.com/company/

He asked if they were still good. They probably are. So, not really a dumb question. There are still a few NAPA stores and small shops around that have a guy that knows how to run the rotor turning machine. The way they do it allows you to keep the bearing races in. (Edit - since the rotor is separate bearings don't come into play, my mistake). Why waste money if you don't have to? Take 'em off, drop 'em off, pick them up in a couple of hours, bolt 'em right back on. It's old school. And, who knows what "new" means these days?

10 initial + 18 vacuum + 20 centripetal = 48. 34 is just initial + centripetal. High PRM cruise could get both vacuum and centripetal max'ed out maybe. What's also interesting is that the PCM/ECM/computer "learns" and holds on to variable to optimize certain things. The O2 sensor feedback probably comes in to play along with EGR. Anyway, finding 50 degrees on a Hyundai is one of those things you probably would never know without the scanner. My point. Once you see it then you can try to figure out why the automotive engineers made it happen.

Kind of looks like a Japanese trademark. not sure. Maybe Denso K________

Most of those parts are still good. Rust "grows" so it looks worse than it is. The rotors can be turned, the hubs are still good on the inside where it matters, the struts can have shocks inserted, etc. The insulators at the tops of the strut are hard to find. The half shafts and u-joints are probably still good. The steering rack rubber looks intact. Lots of good parts there.

How does a person forget about a spare transmission? Don't forget that the first gear ratio matches certain diff ratios best. You might be going back to a better match if the diff was never changed. The close ratios used a 3.9, the wides a 3.54, in general. Not a big deal just something to consider.

Which brand of pressure plate? Any numbers or markings. To be avoided.

This one just belongs here after that one.

Not sure I heard him right or if the media is fixing it for him. Never mind.

Seems to fit, a bit...
