  1. Not for a harness bar. They were the side mount points for the factory 4-point roll bar:
  2. If anyone is expecting to turn up and "race", they'll be disappointed. The 'track sessions' are essentially parade laps.
  3. Where is the "fluid flow", and how much 'flow' is really happening? By definition there will be some movement of fluid at the Master Cylinder end of the equation, but it should be minimal at the business end if everything is working as it should. What you're doing is putting pressure into a fluid. I tend to think of it as like people joining the end of a queue and pushing. Everyone squashes up, and the people at the front of the queue feel the most pain.
  4. It helps if you have it the right way up.... It's the combination Nissan/Prince emblem, introduced after the 1966 merger. It's a monogram with stylised letter 'N' and letter 'P' combined to form a cypher. It was derived from the old single letter 'P' Prince logo, and intended to pay respect to the history of the Prince marque when it came under the wing of the Nissan group. Here it is on the front of the Nissan R382 sports racer. This is the correct orientation:
  5. Stating the obvious again perhaps, but the dimensions are on the car... If you're going to fabricate something yourself, make it to fit your car, not something else.
  6. Rather obviously, the above photos show two different parts. Top photo (that's my photo, I believe...) illustrates the 432-R type 'Undershield', part number 98200-E8700. This was essentially an aero-oriented part, and matches up with a dedicated FRP front apron unique to the 432-R model. Bottom photo is the 99090-N3075 'Under Guard', which was aimed at rally use on L6-powered cars and mounts lower on the car (as rally car ride height was typically higher than stock). It was designed to be a protection-oriented part, rather than aero. Hence its relative thickness at 10mm in comparison to the 432-R's approx 1.5mm thick FRP Undershield.
  7. The BRE rear spoiler was designed in-house by Nissan in 1969, homologated as stock equipment for the PS30-SB 'Fairlady Z432-R' model. BRE simply used the homologated Nissan item on their race cars, then made and sold copies of it.
  8. It'll be either an F5C71-B (5-speed, Direct Drive) or FS5C71-B (5-speed, Overdrive), because there's no such thing as an "FSC5C71B".
  9. An amazing feat considering it's not even running yet... Have you been eating too much cheese again Tony?
  10. The single most important thing about the "Series 1"/"Series 2" thing is that these terms were never used by Nissan. They were invented - retrospectively - in an ad-hoc fashion by 'civilians' in an attempt to make sense of what was actually being misunderstood. It's simple really. There were rolling changes to all models and variants, and some of them are more noticeable than others and/or came at the same time. If you want to make divisions, the single most identifiable one is the change from solid quarter/vented tailgate to vented quarter/solid tailgate.
  11. Don't be too disheartened. This forum has been around a long time and a bit of Darwinian evolution has taken place over the years. Cat vs dog stuff, generally. Despite what you might think, HybridZ has a reputation as a non-nonsense repository of good data. If you are interested in a bit more period (and present) data on rally car suspensions, please feel free to PM me with your direct e-mail address and I'll do my best to help.
  12. "Snide personal comments" like "...your superior pedantry...", perhaps? Seems to me that it depends who they come from... It's interesting to see that you're accusing me of citing John Coffey's name to 'improve my reputation'. I'm not sure you actually understand what's going on here. FACT: Mr Carl Beck - in my experience - knows little to nothing about the factory works rally cars. I see no harm in pointing out that he, and his website zhome, are not a reliable source of hard data about the factory works rally cars and should not be cited as such. FACT: JMortensen brought John Coffey's name into this thread, not me. FACT: Mr John Coffey sought me out as a source for hard data regarding the factory works rally cars and current historic rally cars. He even offered to pay me as a 'consultant' for some of the projects he was working on, which of course I would not hear of, and I was simply happy to help him in any way that I could. Not only was John interested in what others were doing with historic rally suspension in contemporary use within certain sets of regulations, but also he was open-minded enough to be genuinely interested in what the factory works team were doing in period - within the rules and regulations of the time. John being his own man and a great engineer I'm sure that my input was only a very small part of his research and development, but I think he appreciated it and he was kind enough to thank me for it and tell me that it was of use. I see that JMortensen has just provided a link to a previous HybridZ thread in which John discusses the Bilstein inverted 'Monotube' dampers, the type which I shared then-current data with him. FACT: John Coffey gave me some lighthearted advice regarding JMortensen's HybridZ 'persona' (he gave me some wise advice about mine too, actually...). I see no harm in mentioning it when it is so apposite. I see you are predicting what John would have done in this thread, and with me in particular. I think I'll stick with what he actually said and did in my experience.
  13. "Derailed the conversation"? I've provided some real-world references, and can supply more (including what the modern historic rally cars are using) if the OP wants to pursue it. You've supplied a link to zhome... You want the usual JMort pissing contest then? I see you've already refined the OP's request to a "V8 Z", when - as far as I understood it at least - this is not set in stone and the word "Safari" was part of it. You can handle the 'V8 Z' part I'm sure, but I think you'll be way out of your depth with the 'Safari', 'factory cars' and 'period cars' parts. Except to tell us all how crap they were, of course. John Coffey predicted just this. It's a HybridZ trope.
  14. Sometimes I wonder if you do the same thing when (if) you walk around vintage race paddocks? And how about museums? Ever visit them, or is it too much for your bladder to cope with? Ironic that you should mention the sadly missed John Coffey in this thread. He had an open and inquisitive mind about such things, and I discussed the details of Nissan's works rally cars with him over quite a long period. There's always something to be learned from the way things were done in the past, even if it demonstrates how NOT to do something. John made me ROFL with a couple of anecdotes when your name came up in conversation too...
