We (my son and I ran Sakura Garage for 10 years) had a Sherwin Williams Automotive outlet near our shop in Tempe. We bought most of our primer, sealer, and base coats from them. They have all the early Datsun codes and match pretty faithfully IMO. Never liked their clearcoat. We used PPG DCU-2021 for the most part. That's the clear on my 260 - my son shot it in 2012 and it's held up well in the Arizona sun. (My son shot the 304 over dark grey sealer - it added "depth" to the color. Shot over lighter primer or sealer, 304's tone is lighter and a little "washed out")

A little different in the shade. My early 260 in front of Peppers late 260...

A good hose company will be able to make whatever you need.

Yup

I heard one time that it's important to "lap" new baulk rings (synchros) in when installing. True? (like you would lap a valve?)

Mine was the heater core itself but my on my son's '76 it was the valve. He replaced the valve and hoses. I'm an Idaho boy in Arizona so I've never needed a heater - mine is blocked off... I'm not looking forward to replacing that heater core. Check it all though, you'll only want to do it once.

I believe that blue wire should have a Female Bullet connector on it's end. (that's what I have in my notes) It ties to the RL (Red/Blue) wiring for the gauge lighting but I'm not positive what it connects to in/near the center console... It will (should) have battery voltage when the lighting is on. As far as I know it would have nothing to do with A/C. My best guess would be Radio lighting... (I just built a new 240Z dash harness and ran into this exact thing. I have pictures of the same connections from the stock harness - I had to chuckle when I saw your pics...)

I ran my stock 3.36 R180 with a close ratio ZX 5-speed in my 260Z for years before swapping the diff to an 3.54 R200. I loved it, but it was also sitting behind an L28ET so, big torque difference. Like Dave, I now run 3000 RPM at 80 MPH. But, I've always believed that you use the lower 4 gears for spirited driving - 5th for cruising.

No wonder Nissan started using a fuel temperature sensor on the VG30E...

Me too...

I doubt there is, the early 5-speed uses the same basic parts as the 4-speed and adds an overdrive gear. I've used a late 280ZX close-ratio Nissan 5-speed behind my L28ET for several years but I'm relatively easy on it... I also have a T-5. Want me to ship it to you?

My son resin printed me some. Not perfect, but cheap.

That's what's in my close ratio right now. Although many have reported good results with Redline, it didn't work well in mine. IDK why. I'm going to try the Delco Friction Modified gear oil next change.

It holds the padded horn "button" in place.

If you're still looking, I'll go through my stash. I have a few working clocks but I think they're mostly from earlies. '77-'78 are pretty rare here. I do have a working original '78 Quartz clock but I don't know that I want to give that up...

I'm blinded...

That's correct - and the shift lever has a spring and different bushings than the early transmissions.

11 bothered me because it's not an even number. 11 turns of the crank turns the cam 5.5 turns, right? How can the dot line up with the link other than on a full turn? 110 chain links / 40 teeth on the cam = 2.75 cam revolutions for one complete chain revolution. 2 complete chain revolutions = 5.5 cam revolutions. 4 chain revolutions = 11 cam revolutions. 11 cam revolutions = 22 crank revolutions. 11 cam revolutions * 40 teeth = 440. 22 crank revolutions * 20 teeth = 440. 440 is the first number we can get to that is evenly divisible by 110 chain link holes, 20 crank teeth, and 40 cam teeth - isn't it? (110, 220, 330, 440) Somebody check my math - and logic... (11 cam revolutions bothers me - because it isn't even.)

What?? And that makes sense to you why?

I've been wondering (but haven't asked): Why the R35 coils?

Ah, looks nice. I'll stick with an optical wheel in an L28ET dizzy though...

You certainly don't...

It certainly is. Bunny Ears... (ish)

Well, any crank wheel is enough to run it all, but how... What madkaw is getting at is this: The crank travels two complete rotations to complete one engine cycle of "four strokes". Top Dead Center occurs two different times during the complete engine cycle. With a toothed wheel attached to it, the crank can "tell" you when TDC has been reached BUT it can't actually determine if it's on the compression stroke or the exhaust stroke. (no matter how many teeth you have, or lose...) Usually we go to the Cam for that information - it runs at half the crank speed. Since the Cam only makes one rotation for every two crank rotations, a separate sensor on it can tell you when TDC is on the compression stroke - and that's what we're most interested in. Those of us running full sequential ignition with most aftermarket ECU's need input from both the crank and the cam to provide the exact engine position needed. There are other methods I'm sure, but those are most common. Using just the crank toothed wheel input, I could still run individual coils (COP) in a "wasted spark" mode - and the Haltech ECU is certainly capable of doing that. Wasted spark fires two spark plugs at the same time on opposing cylinders so it doesn't really matter the crank position. It's firing cylinder one at both TDC compression and TDC exhaust - it can't "get it wrong". (How could it "get it wrong"? The engine doesn't stop at the same place every time. When you shut it off, the ECU can't keep track of it's exact location and "know" it's exact position when you start it back up again - that's why they need position sensors...) IF Haltech can glean enough information from a toothed wheel (not using a cam sensor input) to run full sequential (not wasted spark), I think there are many that would like to know how they do it. (BTW, I can't see how the Hoke toothed wheel is 60-2... On the linked site it shows his as a typical 36-1. Not that the number of teeth makes any difference. More teeth normally just means better resolution but more teeth can also be harder to "read" accurately at high RPM - so they strike a balance when they invent these things.)
