You heard of El Chapo from the South? I am El-Cheapo from the North 🙂 I just used copper pipe. (Not good as the solder melts in the heat 😞 ) Here is a bad drawing. The longer 1/2" pipe is open on the left and the exhaust gas enters there. It goes though 4 90 degree elbows (hard to draw) to turn the gas 180 degrees and also to allow the two long pipes to squeeze together. The gas then enters the T, travels up the 2nd 1/2" pipe (capped) and scavenging pulls the exhaust out through a hole in the side. The T has a thick copper adapter inside. I could thread this with a tap. The O2 sensor goes in. I believe I used a spark plug thread cleaner as the tap as it was the same thread. If I were to do it again, I'd make it out of aluminum and thread the pipe joints. The U turn/ sensor mount would be a drilled block. I'd also dill a hole where you could safety-wire it to the hatch mechanism.

Still waiting 😞

The trick with the tail pipe measurement is to use a long test pipe that goes deep into the muffler and samples exhaust gas-only. The commercial one is short and allows dilution of the exhaust with ambient air.

1961 Ferrari 196 is reported to be first on one web site Brock knew about the effect early and applied to the Daytona Coupe in 1964. Perhaps that is the mix-up in Nissan origin or perhaps he got involved in 69 with Nissan spoilers as he raced the roadster for them and may have passed on some advice... I guess it could have been a 2 way street but I don't want to make a 2nd Goertz.

I'm trying to find an earlier bolt-on spoiler but this may be the first application. Shelby and Ferrari along with some USA cars had integrated spoilers and wings earlier but Nissan may have had a first bolt-on. Did the Skylines have spoiler accessories at this time?

For completeness: 432R at 1969 Tokyo Motor Show. I will guess it has spoiler. It would be nice to see photos of this. B Blue LHD at Tokyo Motor Show 1969 Mid Jan (18) 1970 Suzuka shows the spoiler on this factory 432R.

Many thanks. That's the one. Nice to see what Nissan did in 69. I was going to scrutinize the 432 pictures for a spoiler 🙂 Thanks for checking. I was a bit surprised to see it in the USA too so I figured I'd look around to see if there were more examples of it in 69. The wind tunnel tests (full and small scale) show the direction of Nissan in (67/68)? Wings on cars go back to ~1928 but they did not come back to racing until mid-late 60's (When Nissan was developing aero parts for the Z)... nice! This may be the blue one shown at the 69 Tokyo Motor Show.

I think they tested many parts in many places. The spoiler in the photo I posted is not in others from North America in 69 so they were testing it somehow. btw do you have photos of, or a link to, that 432 article in Oct or Nov 1969 that Kats posted? I was wondering if a spoiler was in that piece. It was real track testing of the 432 by a Nissan factory racer if I recall. btw II: I'm glad they did not try the spoiler in Canada in the snow at high speeds with no air dam... can you imagine the front end lifting in snow!!!

Opps, you are correct, Typing toofast and too early #6 was bob's greenie.
-
Great observation! Probably similar going on in Sapporo Japan to prepare for Euro Rallies Q1 1970?.
-
WOW! How is Jai? Please say hi if anyone is in contact.

Most early Z's had clear glass but testing parts show defrost wires.

1969 production figures from @kats The one in August and one in September were most likely HLS30-00004 & 5 used as test mules (un-badged) in North America (unless they started at HLS30-00000).
Beware! Some 240z repair kits with gaskets and needles sold for early 240z are too rich. The needles may be made for later 240z with flat tops or even another SU application such as the roadster. Both @Captain Obvious and I had these. The rest of the kit was ok.
@Carl Beck's excellent documentation: So it looks like 587 was the last in 69.
640 in Jan 1970
Some Early HLS30 Vins for North America were held up in the factory and dated later. Here is 503 in Nov 69
This is what I always saw in Ireland:
I just zoomed in... yours are from Japan!
I can almost smell that photo! I like Falken Tires.... some are made in Japan too.
Wow you don't see many pick-up trucks in Europe! And a Ford at that!
