Here is a good frame with the front grill. The bulge in the hood does not seem as pointy too.... but it could be lighting. Perhaps rubber in front centre of bumper too.

@kats Yes! It looks like rubber is in centre! Great observation!

Kats, I am glad you see this. I too thought it looked like rubber in middle but I guessed it was just a strange reflection. I think you are correct though. I'll look at video again and see if I can find a better frame to capture. 1 sec.

WOW... you amaze!

No problem Alan. For searching Z content in Japan, here is my approach: Searching Google's Japanese web site. Searching only web content in Japan by IP correlation Searching using Japanese text and expressions The results are nearly always from Japan. For anyone interested in this, here is a direct link to the configured search site. Just pop in your Japanese text and you will have the 3 filters above working for you: https://www.google.co.jp/search?q=ロールバー+S30&lr=&cr=countryJP&hl=en&tbs=ctr:countryJP&source=lnms&tbm=isch&sa=X&ved=2ahUKEwi_kpCgzrfmAhXRs1kKHSaACFAQ_AUoAXoECAwQAw&biw=2049&bih=1007&dpr=0.67 I do some searching for research and some for fun. The strange sun worshiper Z came out of one of the searches as an artifact. I'll try and dig it up again and post the web site. I'd be grateful if you could translate and explain more about this unique finding!

Thanks Kats! I tried to get the video a few years ago but no luck. I'll try again. From just looking at the minute of testing video on the Nissan web site, there are many interesting details to investigate. That early roll bar is one for sure. If you look closely, it seems to have the side mount points (but not on wheel well) and the two vertical bars to the hatch floor like the production roll bar. Mr. Miyazaki is a true Nostalgic Hero; just like all of the others involved in the project! It is nice when you can identify the person in these old videos and make all of the connections. I am guessing the testing of the silver car may be spring 1968?

The Hoover picked it up in Japan.

The dash certainly is not the final design. The top of the radio/heater cluster extends out much farther into the cabin and the margins are not as filleted nor the edges as smoothed. Here is another interesting pre-production dash:

Here is one example of tail lights (and dual exhaust) in Aug-Oct 1967 designing period. Note the license light in the bumper and keyhole in the hatch lip. Shark gills are a bit obvious.

Thanks for the great info Kats! I am hoping you can help translate the 73 RAC specs. For rows 1 to 4, it seems 1. Valve Architecture = SOHC 2. Displacement= 2498cc 3. Bore = 84.8 Stroke= 73.7 4. Compression Ratio= 11.0 What are the last 5 rows? 5. Horse power= ~250 ??? RPM = 8000 6. ?? ?? ?? ?? 7. Cam Duration ?? ?? 8. ?? ?? 9. ?? 10. ?? THANKS!

@kats A few videos are available for testing a later silver RHD but the LHD test car below seems to be much earlier. The vinyl top option is known but interesting to see on an early test car. The more striking observation is the early rear panel. They either dug up an early prototype for the test or the testing was started well before the Z styling was finalized. But.... is that a roll cage inside? Spoiler testing too + locking fuel door. LHD too but with a single RH wing mirror (round type) and a LH door mirror (A racing 432R also has a similar wing set up but w/o the mirrors fitted). It was an automatic car with black plastic wheel Can't see the hazard switch type lol Note roll bar like silver tube visible in quarter window. @Carl BeckPerhaps to help with USA roll-over test compliance? Same tail section for dirt road test area Orange turn lights and 6 vertical grill supports! (this may be the original grill that went below bumper that Mr Matsuo mentioned. Same car as in wind tunnel with RH wing mirror and LH door mirror. Perhaps an overflow bottle on left? Very narrow rubber strips on over-riders. No diamond vinyl yet and strange metal tube bolted below quarter window... roll bar? If so, you can see where it fastens. I wonder if it ties into the roof where the mystery nut-serts are. No hatch sill or latch, just a thing vertical metal sheet. Another LHD doing water tests but with wooden steering wheel and square wing mirrors Pre 1969 engine and suspension. Note plastic fan, paint dabs, orange oil filter Very early fuel rail with return at rear carb and smog pump No text on valve cover Rear differential and suspension

Cool. I missed the dual function. Thanks!

I just looked at a spare I have. On the front says NILESJAPAN TYPES On the side it has 1617 <perhaps a date code? It has FLASH and a narrow body with a short lead to a 6pin plug like this one from @kats

I hazard to guess... I still think different manufacturers of the plastic stick part is a possibility This is like the early hub caps and the two locations of the valve holes on spoke and between spokes.

I reused the 3 large paper gaskets on an early transmission rebuild. Aviation gasket sealer did the job nicely. Just coat the gasket surface AND the mating surface then wait 5min before fastening together.
